NP ********************************* * SCREEN DESIGN SYSTEM OVERVIEW * ********************************* THE SCREEN DESIGN SOFTWARE PACKAGE CONTAINS FIVE PROGRAMS CREATED TO MINIMIZE THE TIME REQUIRED TO DEVELOP AND MAINTAIN SCREEN LAYOUTS FOR ONLINE APPLICATIONS. THE AUTHOR HAS BEEN A SYSTEMS ANALYST FOR OVER TEN YEARS AND HAS BEEN FRUSTRATED BY THE AMOUNT OF TIME REQUIRED TO DESIGN AND MAINTAIN SCREEN LAYOUTS MANUALLY. THE AUTHOR HAS DONE PROGRAMMING FOR PCS AND A NCR VRX MAINFRAME. THIS PACKAGE DOES NOT INCLUDE LOTS OF BELLS AND WHISTLES, BUT THE AUTHOR BELIEVES IT GETS THE JOB DONE. THERE ARE MANY PC SCREEN HANDLING SOFTWARE PACKAGES ON THE MARKET TODAY, BUT THEY OFTEN REQUIRE SPECIAL SOFTWARE TO WORK. THE AUTHOR WORKS FOR A SCHOOL DISTRICT WITH OVER 40 IBM PC COMPATIBLES. THIS MAKES EXISTING PC SCREEN HANDING PROGRAMS VERY EXPENSIVE WHEN LICENCED ON A PER MACHINE BASIS. MAINFRAME SCREEN HANDLING PROGRAMS ALSO ARE AVAILABLE BY GENERALLY ARE EXPENSIVE AND/OR TAKE A DEGREE OF PROCESSOR TIME TO WORK. THIS SCREEN DESIGN PACKAGE CREATES GENERIC COBOL WORKING-STORAGE SCREEN DEFINITIONS WHICH DO NOT NEED SPECIAL SOFTWARE TO OPERATE. THIS GENERIC SCREEN DEFINITION CAN BE USED ON MAINFRAMES, MINICOMPUTERS AND PCS. NP THE FOLLOWING TABLE SHOWS SCREEN DESIGN PROGRAMS AND AND THEIR FUNCTIONS.

NP ********************** * THE SDMENU PROGRAM * ********************** SDMENU ALLOWS THE USER TO SWITCH QUICKLY AND EASILY BETWEEN THE DIFFERENT SCREEN DESIGN PROGRAMS. WHEN SDMENU CALLS THE OTHER PROGRAMS IN THE SCREEN DESIGN SOFTWARE PACKAGE, IT PASSES THE COMMAND LINE INFORMATION REQUIRED FOR THE OTHER PROGRAMS TO FIND THE SCREEN DESIGN CONFIGURATION FILE. LOADING SDMENU -------------- THE SDMENU PROGRAM IS CALLED FROM THE DOS PROMPT. WHEN SDMENU IS CALLED, THE DOS COMMAND LINE MUST CONTAIN THE SUBDIRECTORY INFORMATION REQUIRED FOR THE PROGRAMS TO FIND THE SCREEN DESIGN CONFIGURATION FILE. THIS COMMAND LINE PATH INFORMATION IS THEN PASSED TO ALL OTHER SCREEN DESIGN PROGRAMS. THE USER IS NOT REQUIRED TO USE SDMENU TO CALL UP ANY OTHER SCREEN DESIGN PROGRAMS. EXAMPLES: SDMENU C:\SD OR SDEDIT C:\SD IF THE SCREEN DESIGN CONFIGURATION FILE IS IN THE DEFAULT DIRECTORY, NO COMMAND LINE INFORMATION IS ENTERED. EXAMPLES: SDMENU OR SDMENU C:\SD THE AUTHOR RECOMMENDS THE USER CREATE A BAT FILE AND PUT IT INTO A DIRECTORY THAT HAS BEEN DESIGNATED BY THE PATH DOS COMMAND. THE USER THEN ONLY NEEDS TO ENTER THE BAT FILE NAME TO LOAD THE SCREEN DESIGN SOFTWARE FROM ANY DISK AND SUBDIRECTORY. FOR EXAMPLE THE USER COULD CREATE A SDM.BAT FILE TO INSTRUCT DOS TO ACCESS C:\SD SUBDIRECTORY. THE PROCEDURE IS AS FOLLOWS: 1. INSERT SCREEN DESIGN FLEX DISK IN THE A FLEX DRIVE. 2. ENTER <C:> TO ACCESS THE HARD DISK. 3. ENTER <MKDIR SD> TO CREATE A SCREEN DESIGN SUBDIRECTORY. 4. ENTER <CD SD> TO ENTER THE SCREEN DESIGN SUBDIRECTORY. 5. ENTER <COPY A:*.* /V> TO COPY SCREEN DESIGN SOFTWARE INTO SUBDIRECTORY. 6. ENTER <CD ..> TO EXIT SUBDIRECTORY. 7. ENTER <CD DOS> TO GO INTO DOS SUBDIRECTORY. 8. CREATE SDM.BAT FILE BY ENTERING <EDLIN SDM.BAT> 9. ENTER <#I> TO ENTER EDLIN'S ADD MODE. 10. ENTER <C:\SD\SDMENU.COM C:\SD\> TO CREATE COMMAND LINE. 11. ENTER <CTRL Z> TO EXIT EDLIN'S ADD MODE. 12. ENTER <E> TO EXIT EDLIN. 13. ENTER <CD ..> TO EXIT DOS SUBDIRECTORY. 14. ENTER <SDM> TO CALL UP SCREEN DESIGN SOFTWARE. NP ********************** * THE SDEDIT PROGRAM * ********************** THE SDEDIT PROGRAM IS USED TO CREATE, EDIT AND PRINT SCREEN LAYOUTS. USE SDEDIT TO DEVELOP YOUR SCREEN LAYOUTS. SDCOBOL HAS VERY LIMITED SCREEN EDITOR FUNCTIONS. LOADING SDEDIT -------------- THE SDEDIT PROGRAM CAN BE CALLED FROM THE SDMENU PROGRAM OR FROM THE DOS PROMPT. WHEN SDEDIT IS CALLED FROM THE DOS PROMPT, THE DOS COMMAND LINE MUST CONTAIN THE SUBDIRECTORY INFORMATION REQUIRED FOR SDEDIT TO FIND THE SCREEN DESIGN CONFIGURATION FILE. EXAMPLE: SDEDIT C:\SD IF THE SCREEN DESIGN CONFIGURATION FILE IS IN THE DEFAULT DIRECTORY, NO COMMAND LINE INFORMATION IS ENTERED. IF SDEDIT IS UNABLE TO FIND THE SCREEN DESIGN CONFIGURATION FILE THE USER WILL BE ASKED TO CONTINUE THE EDIT SESSION. ENTERING <N> WILL CAUSE THE SDEDIT PROGRAM TO TERMINATE. ENTERING <Y> WILL CAUSE THE SDEDIT TO USE DEFAULT VALUES. THE SDEDIT EDITOR ----------------- SDEDIT'S EDITOR IS DESIGNED TO CREATE SCREEN LAYOUTS. IF YOU ARE FAMILIAR WITH TEXT PROCESSING EDITORS, YOU CAN EASY LEARN HOW TO USE SDEDIT. SDEDIT USES LINE 25 AS ITS STATUS LINE. LINE 25 IS ALSO USED FOR DIALOG BETWEEN THE USER AND THE PROGRAM WHEN FUNCTION KEY OPERATIONS ARE BEING PERFORMED. LINES 1 TO 24 SHOW THE SCREEN LAYOUT BEING EDITED. NP CURSOR MOVEMENT KEYS -------------------- THE FOLLOWING TABLE SHOWS THE LIST OF CURSOR MOVEMENT KEYS AVAILABLE IN THE SDEDIT PROGRAM. EDITOR COMMANDS ----------------------------------------------------------- LEFT ARROW MOVE CURSOR LEFT 1 CHARACTER CTRL LEFT ARROW MOVE TO COLUMN 1 OF CURRENT LINE RIGHT ARROW MOVE CURSOR RIGHT 1 CHARACTER CTRL RIGHT ARROW MOVE CURSOR TO COLUMN 80 OF CURRENT LINE UP ARROW MOVE CURSOR UP 1 LINE DOWN ARROW MOVE CURSOR DOWN 1 LINE ENTER KEY MOVE CURSOR TO COLUMN 1 OF NEXT LINE HOME KEY MOVE CURSOR TO LINE 1 CURRENT COLUMN END KEY MOVE CURSOR TO LINE 24 CURRENT COLUMN BACKSPACE KEY DELETE CURRENT CHARACTER AND MOVE CURSOR LEFT 1 CHARACTER DELETE KEY DELETE THE CURRENT CHARACTER FORWARD TAB MOVE CURSOR TO 1ST SPACE CHARACTER AFTER THE NEXT CHARACTER STRING REVERSE TAB MOVE CURSOR TO 1ST SPACE BEFORE CHARACTER OF PREVIOUS CHARACTER (SHIFT TAB) ----------------------------------------------------------- LINE 25 STATUS LINE ------------------- L XX C XX --------- LINE 25 COLUMNS 2 THRU 10 DISPLAYS THE CURSOR'S LINE AND COLUMN POSITION. INS / OVR ---------- DISPLAYS IN COLUMNS 12 THRU 14 OF LINE 25 WHETHER THE EDITOR IS IN INSERT OR OVERSTRIKE MODE. PRESSING THE <INS> KEY WILL SWITCH THE EDITOR BETWEEN THE INSERT AND OVERSTRIKE MODE. INSERT MODE ALLOWS YOU TO TYPE CHARACTERS IN ANYWHERE, WITHOUT LOSING ANY CHARACTERS TO THE RIGHT OF THE CURSOR. WHEN THE EXISTING TEXT IS PUSHED INTO COLUMN 80 OF THE CURSOR LINE THE EDITOR WILL SOUND THE BELL. CHARACTERS TYPED IN OVERSTRIKE MODE WILL REPLACE THE CHARACTER UNDER THE CURSOR. NP B XX XX XX ---------- LINE 25 COLUMNS 16 THRU 24 DISPLAYS THE LINE NUMBER, AND BEGINNING AND ENDING COLUMN NUMBERS OF THE MARKED BLOCK. THE MARKED BLOCK WILL NOT BE HIGHLIGHTED UNTIL A BLOCK OPERATION IS PERFORMED. 1MB THRU 10EXIT --------------- LINE 25 COLUMNS 25 THRU 66 DISPLAYS THE HELP MENU FOR FUNCTION KEY OPERATION EXPLAINED BELOW.

BLOCK COMMANDS -------------- F1 MARK BLOCK BEGIN ------------------- MARKS THE BEGINNING OF A BLOCK. THE END OF THE MARKED BLOCK IS DEFAULTED TO COLUMN 80 UNLESS THE F2 MARK BLOCK END KEY IS USED. ONLY 1 LINE OF TEXT CAN BE MARKED AT TIME. THE LINE AND COLUMNS OF THE MARKED BLOCK ARE DISPLAYED ON LINE 25 COLUMNS 16 THRU 24. COLUMNS 17 AND 18 SHOWS THE MARKED LINE NUMBER. COLUMNS 20 AND 21 DISPLAYS THE BEGINNING COLUMN OF THE MARKED BLOCK. COLUMNS 23 AND 24 DISPLAYS THE ENDING COLUMN NUMBER OF THE MARKED BLOCK. F2 MARK BLOCK END ----------------- MARKS THE ENDING OF A BLOCK. ONLY TEXT ON 1 LINE CAN MARKED AT A TIME. THE END OF A MARKED BLOCK MUST BE ON THE SAME LINE AS THE MARK BLOCK BEGIN AND BE TO THE RIGHT OF THE BLOCK BEGIN COLUMN ELSE A BEEP WILL SOUND. F3 COPY MARKED BLOCK -------------------- COPIES THE MARKED BLOCK DATA TO THE CURSOR'S LINE AND COLUMN. THE LENGTH OF THE COPY IS THE SHORTER OF THE LENGTHS; THE MARKED BLOCK, OR 80 MINUS THE CURRENT CURSOR POSITION. THE SCREEN DISPLAYS HOW THE SCREEN WILL APPEAR IF THE COPY OPERATION IS PERFORMED. BOTH THE COPY FROM BLOCK AND THE COPY TO AREA OF THE SCREEN ARE HIGHLIGHTED. TO COMPLETE THE COPY OPERATION ENTER <Y> TO THE COPY BLOCK MESSAGE. TO ABORT THE COPY OPERATION ENTER <N>. F4 SWAP MARKED BLOCK -------------------- SWAPS THE MARKED BLOCK DATA WITH THE DATA STARTING AT THE CURSOR'S LINE AND COLUMN. THE LENGTH OF THE SWAP IS THE SHORTER OF THE LENGTHS; THE MARKED BLOCK, OR 80 MINUS THE CURRENT CURSOR'S POSITION. THE SCREEN DISPLAYS HOW THE SCREEN WILL APPEAR IF THE SWAP OPERATION IS PERFORMED. BOTH THE SWAP FROM BLOCK AND THE SWAP TO AREA OF THE SCREEN ARE HIGHLIGHTED. TO COMPLETE THE SWAP OPERATION ENTER <Y> TO THE SWAP MESSAGE. TO ABORT THE SWAP OPERATION ENTER <N>. LINE SWAP FEATURE ----------------- ALLOWS THE USER TO SWAP THE TEXT TO THE LEFT OF THE CURSOR'S POSITION WITH THE TEXT TO THE RIGHT OF THE CURSOR ON THE SAME LINE. TO USE THIS LINE SWAP FEATURE POSITION THE CURSOR AT COLUMN 1 OF THE LINE TO SWAP AND PRESS <F1>. MOVE THE CURSOR TO THE LAST COLUMN OF THE LINE TO BE SWAPPED AND PRESS <F2>. MOVE THE CURSOR RIGHT 1 COLUMN BY PRESSING THE <RIGHT ARROW> KEY. PRESS <F4> TO PERFORM THE SWAP. ENTER <Y> TO THE SWAP MESSAGE. TO SWAP COLUMNS 1 THRU 20 OF LINE 3 WITH COLUMNS 21 THRU 80 OF LINE 3 DO THE FOLLOWING: 1. MOVE CURSOR TO LINE 3 COLUMN 1. PRESS <F1> TO MARK THE BLOCK. 2. MOVE CURSOR TO LINE 3 COLUMN 20 AND PRESS <F2> MARKING THE END OF THE BLOCK. 3. MOVE THE CURSOR TO LINE 3 COLUMN 21 BY PRESSING THE <RIGHT ARROW> KEY. 4. PRESS <F4> TO PERFORM THE LINE SWAP. 5. ENTER <Y> TO THE SWAP HIGHLIGHTED BLOCKS. THE DATA FROM COLUMNS 21 THRU 80 WILL BE MOVED TO COLUMNS 1 THRU 60, AND THE TEXT FROM COLUMNS 1 THRU 20 WILL BE MOVED TO COLUMNS 61 THRU 80. F5 INSERT LINE -------------- ALLOWS THE USER TO INSERT A BLANK LINE TO THE LEFT OF THE CURSOR, RIGHT OF THE CURSOR, OR A COMPLETE BLANK LINE ABOVE THE CURSOR'S LINE. IF THE CURSOR IS AT COLUMN 1 OR COLUMN 80, ONLY A COMPLETE LINE INSERT IS ALLOWED. IF THE CURSOR IS NOT AT COLUMN 1 OR COLUMN 80 THE EDITOR ALLOWS THE USER TO PERFORM A LINE SPLIT INSERT. ENTERING <L> TO THE INSERT LINE MESSAGE MOVES THE LINE LEFT OF THE CURSOR POSITION INCLUSIVE DOWN 1 LINE AND A PARTIAL BLANK LINE IS INSERTED. ENTERING <R> TO THE INSERT LINE MESSAGE MOVES THE LINE RIGHT OF THE CURSOR POSITION INCLUSIVE DOWN 1 LINE AND A PARTIAL BLANK LINE IS INSERTED. ENTERING <Y> TO THE INSERT LINE MESSAGE INSERTS A COMPLETE BLANK LINE ABOVE THE CURSOR'S LINE REGARDLESS OF THE CURSOR'S COLUMN POSITION. NP WHEN A LINE IS INSERTED AND THE EDITOR PUSHES LINE 24 OFF OF THE SCREEN, IT REMAINS IN A BUFFER AND WILL REAPPEAR A IF LINE DELETION IS MADE. A MAXIMUM OF 6 LINES ARE SAVED IN THE BUFFER. F6 DELETE LINE -------------- THE F6 FUNCTION KEY ALLOWS THE USER TO DELETE THE LINE TO THE LEFT OF THE CURSOR, RIGHT OF THE CURSOR, OR THE COMPLETE CURSOR LINE. IF THE CURSOR IS AT COLUMN 1 OR COLUMN 80, ONLY THE COMPLETE LINE DELETE IS ALLOWED. IF THE CURSOR IS NOT AT COLUMN 1 OR COLUMN 80 THE EDITOR ALLOWS THE USER TO DO A SPLIT LINE DELETION. ENTERING <L> TO THE DELETE LINE MESSAGE DELETES THE LINE LEFT OF THE CURSOR POSITION INCLUSIVE AND ALL TEXT BELOW IS MOVED UP ONE LINE. ENTERING <R> DELETES ALL TEXT RIGHT OF THE CURSOR POSITION INCLUSIVE AND MOVES ALL TEXT BELOW THE CURSOR UP 1 LINE. ENTERING <Y> TO THE DELETE LINE MESSAGE DELETES A COMPLETE LINE REGARDLESS OF THE CURSOR'S COLUMN POSITION. WHEN A LINE IS DELETED AND THE EDITOR MOVES LINE 24 UP A LINE, THE LAST LINE PUSHED INTO THE BUFFER WILL REAPPEAR. F7 ZAP ------- ALLOWS THE USER TO ERASE ALL TEXT ABOVE, BELOW, LEFT OF CURSOR, RIGHT OF CURSOR, OR ERASE THE CURSOR LINE. THE ZAP FUNCTION DOES NOT DELETE OR INSERT LINES, IT JUST RESETS THEM TO SPACES. ENTERING <A> WILL ERASE ALL LINES ABOVE, AND ALL TEXT TO THE LEFT OF THE CURSOR. ENTERING <L> WILL ERASE ALL TEXT TO THE LEFT OF THE CURSOR INCLUSIVE ON CURSOR LINE ONLY. ENTERING <B> ERASES ALL LINES BELOW THE CURSOR AND ALL TEXT TO THE RIGHT OF THE CURSOR INCLUSIVE. ENTERING <Y> WILL ERASE ALL TEXT ON THE CURSOR'S LINE. F8 JUSTIFY TEXT --------------- ALLOWS THE USER TO LEFT JUSTIFY, RIGHT JUSTIFY, OR CENTER THE CURSOR'S LINE. THIS ALLOWS THE USER TO CENTER HEADINGS. PRESS THE <F8> FUNCTION KEY AND ENTER THE DESIRED OPTION. ENTERING <L> WILL PLACE THE FIRST NONSPACE CHARACTER OF THE LINE IN COLUMN 1. ENTERING <R> WILL PLACE THE LAST NONSPACE CHARACTER IN COLUMN 80. ENTERING <C> WILL CENTER THE TEXT. F9 PRINT OR MAP SCREEN ---------------------- ALLOWS THE USER TO PRINT OR MAP THE SCREEN. THE SCREEN CAN BE PRINTED OR MAPPED TO THE PRINTER OR A DISK FILE. THE DISK FILE OPTIONS PERMITS THE USER TO USE A SIDEWAYS PRINT PROGRAM, OR LOAD THE SCREEN INTO A WORD PROCESSOR DOCUMENT. THE <P> PRINT SCREEN OPTION PRINTS THE SCREEN WITH DATE AND TIME AND BORDERS ABOVE AND BELOW ONLY. THIS ALLOWS THE USER TO PRINT THE SCREEN IN PICA MODE ON A NARROW CARRIAGE PRINTER. THE <B> PRINT OPTION PRINTS A COMPLETE BORDER AROUND THE SCREEN. NARROW CARRIAGE PRINTERS MUST BE IN ELITE OR COMPRESS PRINT MODE. WIDE CARRIAGE PRINTERS CAN PRINT THE SCREEN IN PICA. A BOARDER PRINT CONTAINS 82 CHARACTERS. THE <M> PRINT OPTION OUTPUTS THE SCREEN WITH EACH CHARACTER PRINTED INSIDE A BOX. THE MAP IS SIMILAR TO CREATING A SCREEN LAYOUT ON A COBOL CODING FORM. TO PRINT DIRECTLY TO A PRINTER THE PRINTER MUST BE A WIDE CARRIAGE. IF PRINTING IS SENT TO A DISK FILE, AND A SIDEWAYS PROGRAM IS DESIGNATED IN THE SCREEN DESIGN CONFIGURATION FILE, SDEDIT ASKS IF THE SIDEWAYS PROGRAM IS TO BE CALLED AFTER THE SDEDIT PRINT PROCESS IS COMPLETE. F10 SAVE AND/OR EXIT -------------------- THE F10 FUNCTION KEYS ALLOWS THE USER TO SAVE THE SCREEN TO DISK AND/OR EXIT THE PROGRAM. PRESSING ONLY THE <ENTER> KEY AT THE SAVE/EXIT MESSAGE WILL RETURN THE USER TO THE EDIT SESSION. PRESSING THE <S> KEY INSTRUCTS SDEDIT TO SAVE THE SCREEN TO DISK AND RETURN TO THE EDIT PROCESS. PRESSING THE <X> KEY INSTRUCTS SDEDIT TO SAVE THE SCREEN TO DISK AND TO EXIT THE PROGRAM. PRESSING <C> WILL CAUSE THE PROGRAM TO SAVE THE SCREEN UNDER ANOTHER NAME AND EXIT THE EDIT SESSION. ENTERING <Q> WILL CAUSE THE PROGRAM TO TERMINATE WITHOUT SAVING THE SCREEN. SHIFT F1 "x" FIELD ------------------- THE SHIFT F1 FUNCTION KEY COMBINATION PERMITS THE USER TO CREATE A FIELD OF SMALL "x"s. THE SMALL "x" IS USED IN SDCOBOL TO DEFINE A COBOL ALPHA-NUMERIC FIELD AS COMPARED TO A SCREEN LITERAL. SDEDIT DETERMINES THE MAXIMUM FIELD SIZE AVAILABLE. PRESSING THE <ENTER> KEY WITHOUT ENTERING A FIELD SIZE WILL ABORT THE "x" FIELD PROCESS. THE OPERATOR ALSO HAS A OPTION TO REJECT THE "x" DEFINITION AFTER IT IS DISPLAYED ON THE SCREEN. SHIFT F2 FIELD SIZE -------------------- THE SHIFT F2 FUNCTION KEY IS USED TO DETERMINE THE SIZE OF A FIELD OR A CHARACTER STRING OF SPACES. THIS FUNCTION IS USED TO MAKE SURE THAT DEFINED SCREEN FIELDS ARE THE PROPER SIZE. THE FIELD SIZE FUNCTION CAN ALSO BE USED TO DETERMINE STRING LENGTHS FOR NON COBOL SCREEN DEFINITION. NP DEFINING FIELDS FOR SDCOBOL --------------------------- THE SDCOBOL PROGRAM GENERATES WORKING-STORAGE SCREEN DEFINITIONS FROM A SCREEN CREATED BY THE SDEDIT PROGRAM. MOST HIGH SPEED MAINFRAME PRINTERS CAN ONLY PRINT CAPITAL LETTERS THEREFORE, SDCOBOL LOOKS FOR LOWER CASE CHARACTERS FOR FIELD DEFINITIONS AND CONVERTS THEM AT COBOL SCREEN GENERATION TIME. COBOL "X" TYPE ALPHA-NUMERIC FIELDS ARE DEFINED IN THE SCREEN DESIGN PROGRAMS AS A LOWER CASE "x". COBOL NUMERIC FIELD ALSO USE LOWER CASE LETTERS AS PART OF THEIR FIELD DEFINITIONS. BECAUSE THERE IS NO LOWER CASE EQUIVALENT OF THE "9" CHARACTER THE "#" IS SUBSTITUTED. ALL NUMERIC FIELDS MUST BEGIN WITH ONE THE FOLLOWING CHARACTERS; "z", "#", OR "$". THE TABLE BELOW SHOWS CHARACTERS ALLOWED IN A COBOL NUMERIC FIELD. SYMBOL DESCRIPTION ---------------------------------------------------------- "#" NOT ZERO SUPPRESSED NUMERIC CHARACTER "z" SUPPRESS LEADING ZERO NUMERIC CHARACTER "$" FLOATING DOLLAR SIGN "." DECIMAL POINT "," COMMA INSERTION CHARACTER "cr" CREDIT AMOUNT "db" DEBIT AMOUNT "+" POSITIVE AMOUNT "-" NEGATIVE AMOUNT "/" DATE INSERTION CHARACTER ---------------------------------------------------------- SDCOBOL FIELD DESCRIPTION EXAMPLES ----------------------------------------------------------- xxxxxxxxxx TEN CHARACTER ALPHA/NUMERIC FIELD ##### FIVE CHARACTER NUMERIC FIELD zzzz# ZERO SUPPRESSED NUMERIC FIELD zzz,zz#.## ZERO SUPPRESSED NUMERIC FIELD WITH DECIMALS $$$,$$#.## DOLLAR AMOUNT NUMERIC FIELD $$$,$$#.##cr CREDIT DOLLAR AMOUNT $$$,$$#.##db DEBIT DOLLAR AMOUNT zzzzz BLANK WHEN ZERO NUMERIC FIELD ##/##/## DATE FIELD ----------------------------------------------------------- FIELDS NOT FOLLOWING THE ABOVE RESTRICTIONS CAN BE EASY CONVERTED TO COBOL FIELDS BY USING THE F1 FUNCTION KEY IN SDCOBOL. NP *********************** * THE SDCOBOL PROGRAM * *********************** THE SDCOBOL PROGRAM IS USED TO GENERATE COBOL WORKING-STORAGE SECTION SCREEN LAYOUTS. THE OUTPUT FILE FROM THIS SCREEN GENERATOR CAN BE COPIED INTO A PC COBOL PROGRAM OR UPLOADED TO A MAINFRAME BY USING A MAINFRAME COMMUNICATION PROGRAM. SDCOBOL HAS VERY LIMITED SCREEN EDITOR FUNCTIONS. SDCOBOL CAN TURN THIS SCREEN INTO THE FOLLOWING COBOL CODE. -------------------------------------------------------------------------------- PAYID PAYROLL EMPLOYEE ID SCREEN SCREEN ID LAST NAME (1)

BE CALLED FROM THE SDMENU PROGRAM OR FROM THE DOS PROMPT. WHEN SDCOBOL IS CALLED FROM THE DOS PROMPT, THE DOS COMMAND LINE MUST CONTAIN THE SUBDIRECTORY INFORMATION REQUIRED FOR SDCOBOL TO FIND THE SCREEN DESIGN CONFIGURATION FILE. EXAMPLES: SDCOBOL C:\SD OR SDCOBOL NP IF THE SCREEN DESIGN CONFIGURATION FILE IS IN THE DEFAULT DIRECTORY, NO COMMAND LINE INFORMATION IS ENTERED. IF SDCOBOL IS UNABLE TO FIND THE SCREEN DESIGN CONFIGURATION FILE THE USER WILL BE ASKED TO CONTINUE THE EDIT SESSION. ENTERING <N> WILL CAUSE THE SDCOBOL PROGRAM TO TERMINATE, <Y> WILL CAUSE THE SDCOBOL TO USE DEFAULT VALUES. THE SDCOBOL EDITOR ------------------ SDCOBOL'S EDITOR IS VERY LIMITED, IT IS DESIGNED TO MAKE ONLY MINOR CHANGES. USE SDEDIT TO CREATE AND EDIT YOUR SCREENS. SDCOBOL USES LINE 25 AS IT'S STATUS LINE. LINE 25 IS ALSO USED FOR DIALOG BETWEEN THE USER AND THE PROGRAM WHEN FUNCTION KEY OPERATIONS ARE BEING PERFORMED. LINES 1 TO 24 SHOW THE SCREEN BEING EDITED. CURSOR MOVEMENT KEYS -------------------- THE FOLLOWING TABLE SHOWS THE LIST OF CURSOR MOVEMENT KEYS FOUND IN THE SDCOBOL PROGRAM: EDITOR COMMANDS ----------------------------------------------------------- LEFT ARROW MOVE CURSOR LEFT 1 CHARACTER CTRL LEFT ARROW MOVE CURSOR TO COLUMN 1 OF CURRENT LINE RIGHT ARROW MOVE CURSOR RIGHT 1 CHARACTER CTRL RIGHT ARROW MOVE CURSOR TO COLUMN 80 OF CURRENT LINE UP ARROW MOVE CURSOR UP 1 LINE DOWN ARROW MOVE CURSOR DOWN 1 LINE ENTER KEY MOVE CURSOR TO COLUMN 1 OF NEXT LINE HOME KEY MOVE CURSOR TO LINE 1, CURRENT COLUMN END KEY MOVE CURSOR TO LINE 24, CURRENT COLUMN BACKSPACE KEY DELETE CURRENT CHARACTER AND MOVE CURSOR LEFT 1 CHARACTER DELETE KEY DELETE THE CURRENT CHARACTER FORWARD TAB MOVE CURSOR TO 1ST CHARACTER OF THE NEXT WORD REVERSE TAB MOVE CURSOR TO 1ST CHARACTER OF THE PREVIOUS WORD (SHIFT TAB) ----------------------------------------------------------- LINE 25 STATUS LINE L XX C XX --------- LINE 25 COLUMNS 2 THRU 10 DISPLAYS THE CURSOR'S LINE AND COLUMN POSITION. OVR --- SDCOBOL ONLY HAS THE OVERSTRIKE OPTION AVAILABLE. 1CBLFLD THRU 10EXIT ------------------- LINE 25 COLUMNS 16 THRU 65 DISPLAYS THE HELP MENU FOR FUNCTION KEY PROCESSES EXPLAINED BELOW. FUNCTION KEY TABLE ---------------------------------------------------------- F1 CONVERT CHARATER-STRING STARTING AT CURSOR POSITION TO A COBOL FIELD F2 CONVERT COBOL FIELD STARTING AT CURSOR POSITION TO A SCREEN LITERAL F3 CHANGE COBOL FIELD NAME OF TEXT AT CURSOR POSITION F4 CHANGE COBOL 01 RECORD LEVEL SCREEN NAME F5 CLEAR COBOL SCREEN AND ALL FIELD NAMES F6 GENERATE COBOL SCREEN DEFINITION F7 CALL UPLOAD COMMUNICATION PROGRAM F10 SAVE SCREEN / EXIT PROGRAM XXXXXXXX.XXX ------------ LINE 25 COLUMN 67 THRU 79 DISPLAYS THE FILE NAME FOR THE SCREEN BEING EDITED. FUNCTION KEYS ------------- F1 CONVERT TEXT TO COBOL FIELD ------------------------------ CONVERTS THE CHARACTER-STRING STARTING AT THE CURRENT CURSOR POSITION TO A COBOL FIELD. SDCOBOL CONVERSION STOPS AT THE END OF THE LINE OR WHEN A NONCONVERTIBLE CHARACTER IS ENCOUNTERED. THE FOLLOWING TABLE LISTS SDCOBOL FIELD CHARACTERS AND CONVERSION. ALL COBOL FIELD CHARACTER-STRINGS ARE HIGHLIGHTED ON COLOR MONITORS AND UNDERLINED ON MONOCHROME MONITORS. COBOL "X" TYPE ALPHANUMERIC FIELDS ARE DEFINED IN THE SCREEN DESIGN PROGRAMS AS A LOWER CASE "x". COBOL NUMERIC FIELDS ALSO USE LOWER CASE LETTERS AS PART OF THEIR FIELD DEFINITIONS. BECAUSE THERE IS NO LOWER CASE EQUIVALENT OF THE "9" CHARACTER THE "#" IS SUBSTITUTED. ALL NUMERIC FIELDS MUST BEGIN WITH ONE THE FOLLOWING CHARACTERS; "z", "#", OR "$". THE REASON LOWER CASE CHARACTERS AND THE "#" ARE USED TO DEFINE COBOL FIELDS IS TO MAKE THE SCREENS DESIGNED BY THIS SOFTWARE AS GENERIC AS POSSIBLE. IF THERE WERE CONTROL CODES IMBEDDED IN THE SCREEN LAYOUT DISK FILES THEY COULD PRODUCE UNEXPECTED RESULTS WHEN LOADED INTO WORD PROCESSORS OR PRINTED. NP THE TABLE BELOW SHOWS CHARACTERS ALLOWED IN A COBOL NUMERIC FIELD. SCREEN COBOL TEXT FIELD DESCRIPTION ---------------------------------------------------------- "X" "x" ALPHANUMERIC FIELD "9" "#" NOT ZERO SUPPRESSED NUMERIC CHARACTER "Z" "z" SUPPRESS LEADING ZERO NUMERIC CHARACTER "$" "$" FLOATING DOLLAR SIGN "." "." DECIMAL POINT "," "," FLOATING COMMA "CR" "cr" CREDIT AMOUNT "DB" "db" DEBIT AMOUNT "+" "+" POSITIVE AMOUNT "-" "-" NEGATIVE AMOUNT "/" "/" DATE SEPARATION CHARACTER ----------------------------------------------------------- SDCOBOL FIELD DESCRIPTION EXAMPLES ----------------------------------------------------------- xxxxxxxxxx TEN CHARACTER ALPHA/NUMERIC FIELD ##### FIVE CHARACTER NUMERIC FIELD zzzz# ZERO SUPPRESSED NUMERIC FIELD zzz,zz#.## ZERO SUPPRESSED NUMERIC FIELD WITH DECIMALS $$$,$$#.## DOLLAR AMOUNT NUMERIC FIELD $$$,$$#.##- CREDIT DOLLAR AMOUNTS $$$,$$#.##cr $$$,$$#.##+ DEBIT DOLLAR AMOUNTS $$$,$$#.##db zzzzz BLANK WHEN ZERO NUMERIC FIELD ##/##/## DATE FIELD ----------------------------------------------------------- F2 CONVERT COBOL FIELD TO SCREEN TEXT ------------------------------------- CONVERTS COBOL FIELD CHARACTERS STARTING AT THE CURRENT CURSOR POSITION TO A SCREEN CHARACTER-STRING. SDCOBOL CONVERSION STOPS AT THE END OF THE LINE OR WHEN A NONCONVERTIBLE CHARACTER IS ENCOUNTERED. THE TABLE ABOVE LISTS SDCOBOL FIELD CHARACTERS AND CONVERSIONS. SCREEN CHARACTER-STRINGS ARE DISPLAYED IN NORMAL VIDEO. F3 CHANGE COBOL FIELD NAME -------------------------- CHANGES THE COBOL FIELD NAME FOR THE CHARACTER STRING AT THE CURRENT CURSOR POSITION. TO REMOVE AN EXISTING COBOL FIELD NAME, TYPE IN THE WORD <CLEAR>. SDCOBOL WILL KEEP THE EXISTING FIELD NAME IF THE <ENTER> KEY IS PRESSED WITHOUT ENTERING A NEW FIELD NAME OR THE WORD <CLEAR>. COBOL FIELD NAMES ARE CHECKED FOR VALID SYNTAX. IT IS NOT NECESSARY FOR FIELD NAMES TO BE ENTERED BEFORE THE F6 SCREEN GENERATION IS PERFORMED. SDCOBOL WILL PROMPT FOR EACH FIELD NAME DURING THE SCREEN GENERATION PROCESS. NP F4 CHANGE COBOL SCREEN NAME --------------------------- CHANGES THE COBOL 01 RECORD LEVEL NAME FOR THE SCREEN. TO REMOVE THE EXISTING SCREEN NAME, TYPE THE WORD <CLEAR>. SDCOBOL WILL KEEP THE EXISTING SCREEN NAME IF THE <ENTER> KEY IS PRESSED WITHOUT ENTERING A NEW SCREEN NAME OR THE WORD <CLEAR>. SCREEN FIELD NAME IS CHECKED FOR VALID SYNTAX. MAXIMUM LENGTH OF SCREEN NAME IS 23 CHARACTERS. SDCOBOL APPENDS THE CHARACTER-STRING "-SCREEN" TO THE SCREEN NAME. EACH LINE WITHIN THE 01 RECORD LEVEL HAS THE SCREEN NAME AND "-LINE-XX" WITH "XX" BEING THE SCREEN LINE NUMBER. THIS ALLOWS THE PROGRAMMER TO EASILY DISPLAY ONE LINE AT A TIME IF MULTIPLE SCREENS ARE USED WITHIN ONE PROGRAM. THE SCREEN NAME IS NOT REQUIRED BEFORE THE F6 SCREEN GENERATION IS PERFORMED. F5 CLEARS COBOL SCREEN NAME AND FIELD NAMES. -------------------------------------------- CLEARS ALL COBOL FIELD NAMES AND THE COBOL 01 RECORD LEVEL SCREEN NAME. F6 GENERATE COBOL SCREEN DEFINITION ----------------------------------- THIS IS THE BREAD AND BUTTER FUNCTION OF THE SDCOBOL PROGRAM. AFTER PROMPTING FOR THE OUTPUT FILE NAME, SDCOBOL GENERATES THE COBOL WORKING-STORAGE 01 SCREEN DEFINITION. THE OUTPUT FILE FROM THIS SCREEN GENERATOR CAN BE COPIED INTO A PC COBOL PROGRAM OR UPLOADED TO A MAINFRAME BY USING A MAINFRAME COMMUNICATION PROGRAM. DURING THE COBOL SCREEN GENERATION PROCESS THE USER IS SHOWN THE PREVIOUS ENTRY FOR THE OUTPUT FILENAME, SCREEN NAME, AND ALL COBOL FIELD NAMES. BY PRESSING ONLY THE <ENTER> KEY THE PROGRAM WILL USE THESE PREVIOUSLY ENTERED VALUES. THIS FEATURE ALLOWS A USER TO QUICKLY REGEN A SCREEN IF AN ERROR HAS BEEN MADE. THE USER CAN HALT THE SCREEN GENERATION PROCESS BY ENTERING <ABORT> TO THE SCREEN NAME OR FIELD NAME PROMPT. THE USER CAN SPECIFY A FILE NAME OF "PRN" IF PRINTER OUTPUT IS DESIRED FOR MANUAL ENTRY INTO A PROGRAM. THE SCREEN NAME AND COBOL FIELD NAMES ARE VALIDATED FOR CORRECT COBOL SYNTAX WHEN ENTERED. THE COBOL FIELD CHARACTER-STRING IS HIGHLIGHTED WHEN SDCOBOL REQUESTS THE COBOL FIELD NAME. SCREEN CONTROL CODES CAN BE GENERATED FOR THE ANSI.SYS SCREEN DRIVER OR FOR THE NCR 796-101 TTY TERMINAL. SEE SDCONFIG INSTRUCTIONS FOR IMPLEMENTATION OF THIS FEATURE. F7 CALL COMMUNICATION PROGRAM ----------------------------- BY PRESSING THE <F7> FUNCTION KEY THE USER CAN UPLOAD THE SCREEN DEFINITION SAVED ON DISK DURING A SDCOBOL SESSION. THE USER CAN ENTER THE UPLOAD PROGRAM TO CALL IN THE SDCONFIG PROGRAM. ALTHOUGH THERE IS A NCR 796-101 COMMUNICATION PROGRAM INCLUDED IN THE SCREEN DESIGN SOFTWARE PACKAGE, THE USER CAN USE OTHER UPLOAD SOFTWARE. NP F10 SAVE AND/OR EXIT -------------------- THE F10 FUNCTION KEYS ALLOWS THE USER TO SAVE THE SCREEN TO DISK AND/OR EXIT THE PROGRAM. PRESSING ONLY THE <ENTER> KEY AT THE SAVE/EXIT MESSAGE WILL RETURN THE USER TO THE EDIT SESSION. PRESSING THE <S> KEY INSTRUCTS SDCOBOL TO SAVE THE SCREEN TO DISK AND RETURN TO THE EDIT PROCESS. PRESSING THE <X> KEY INSTRUCTS SDCOBOL TO SAVE THE SCREEN TO DISK AND TO EXIT THE PROGRAM. PRESSING <C> WILL CAUSE THE PROGRAM TO SAVE THE SCREEN UNDER ANOTHER NAME AND EXIT THE EDIT SESSION. ENTERING <Q> WILL CAUSE THE PROGRAM TO EXIT WITHOUT SAVING THE SCREEN. BECAUSE SDCOBOL GENERATES CLEAN COBOL SCREEN DEFINITIONS SDCOBOL WILL NOT SAVE THE COBOL SCREEN NAME OR FIELD NAMES. NP ************************ * THE SDCONFIG PROGRAM * ************************ THE SDCONFIG PROGRAM IS USED TO CONFIGURE THE OPTIONS WITHIN THE SCREEN DESIGN PROGRAMS. ALL SCREEN DESIGN PROGRAMS USE DEFAULT SETTINGS IF THE CONFIGURATION FILE IS NOT CREATED. THE SDCONFIG PROGRAM CREATES "SDCOLOR.CFG" FOR COLORED MONITORS OR "SDMONO.CFG" FOR MONOCHROME MONITORS. HAVING A SEPARATE FILE FOR EACH TYPE OF MONITOR ALLOWS USERS WITH A MONOCHROME MONITOR RUNNING COLOR SOFTWARE TO CHANGE THE SCREEN COLORS FOR CORRECT SHADING. THE NAME OF THE CONFIGURATION FILE BEING CREATED OR EDITED APPEARS IN THE UPPER RIGHT HAND CORNER OF THE SCREEN. THE SDCONFIG PROGRAM CAN BE CALLED FROM THE SDMENU PROGRAM OR FROM THE DOS PROMPT. WHEN SDCONFIG IS CALLED FROM THE DOS PROMPT, THE DOS COMMAND LINE MUST CONTAIN THE SUBDIRECTORY INFORMATION REQUIRED FOR SDCONFIG TO FIND THE SCREEN DESIGN CONFIGURATION FILE. EXAMPLES: SDCONFIG C:\SD OR SDCONFIG IF THE SCREEN DESIGN CONFIGURATION FILE IS IN THE DEFAULT DIRECTORY, NO COMMAND LINE INFORMATION IS ENTERED. IF SDCONFIG IS UNABLE TO FIND THE SCREEN DESIGN CONFIGURATION FILE THE USER WILL BE ASKED TO CONTINUE THE CONFIGURATION SESSION. ENTERING <N> WILL CAUSE THE SDCONFIG PROGRAM TO TERMINATE, <Y> WILL CAUSE THE SDCONFIG TO USE DEFAULT VALUES. IF THE CONFIGURATION FILE IS NOT FOUND IN THE DEFAULT SUBDIRECTORY THE USER MUST INCLUDE THE PATH FOR THE CONFIGURATION FILE IN THE COMMAND LINE WHEN EXECUTING ANY SCREEN DESIGN PROGRAM, EXCEPT SDCONFIG. ALL BUT THREE ENTRIES IN THE CONFIGURATION FILE ARE TOGGLED TO THEIR DIFFERENT SETTINGS BY PRESSING THE CORRESPONDING FUNCTION KEY. THE THREE ENTRIES WHICH REQUIRE MANUAL ENTRIES ARE; SIDEWAYS PRINT PROGRAM TO USE F9, COMMUNICATION UPLOAD PROGRAM TO CALL CTRL F5, AND CHARACTER DELAY COUNTER ALT F4. SCREEN COLORS ------------- THE <F1> THRU <F7> KEYS AND <SHIFT F1> THRU <SHIFT F7> ALLOW THE USER TO CHANGE THE COLORS FOR THE DIFFERENT PROCEDURES. WHEN USED ON A MONOCHROME MONITOR THE <SHIFT F1> THRU <SHIFT F7> KEYS ARE DISABLED BECAUSE OF THE LIMITED NUMBER OF SCREEN ATTRIBUTE OPTIONS AVAILABLE. PRINTER TYPE F8 --------------- ALLOWS THE USER TO ALTERNATE BETWEEN THE THREE SUPPORTED PRINTER TYPES. "NCR" CONFIGURES THE SCREEN DESIGN PROGRAMS TO SUPPORT A NCR 6411 OR C.ITOH 8510B PRINTERS. "EPSON" CONFIGURES THE PROGRAMS FOR EPSON COMPATIBLE PRINTERS. "IBM" CONFIGURES THE PROGRAMS FOR IBM PROPRINTER COMPATIBLE PRINTERS. SIDEWAYS PROGRAM F9 ------------------- THE F9 FUNCTION KEY ALLOWS THE USER TO ENTER A SIDEWAYS PRINT PROGRAM TO CALL FROM SDEDIT AFTER CREATING A DISK FILE. THE PC MUST HAVE ENOUGH RAM MEMORY FOR BOTH THE SDEDIT PROGRAM AND THE SIDEWAYS PRINT PROGRAM TO USE THIS FEATURE. THIS FEATURE ALLOWS NARROW CARRIAGE PRINTERS TO PRINT SCREEN MAPS SIDEWAYS. SCREEN CONTROL CODES CTRL F1 ---------------------------- HOLDING DOWN THE CTRL KEY TO THE LEFT OF THE "A" KEY AND PRESSING THE <F1> WILL TOGGLE THE DIFFERENT SCREEN CONTROL CODES OPTIONS AVAILABLE IN SDCOBOL. IF "NONE" IS USED NO CONTROL CODES WILL BE GENERATED DURING A COBOL WORKING- STORAGE SCREEN GENERATION PROCESS. MANY COBOL COMPILERS DISPLAY COMMANDS ALLOW THE USER TO CONTROL LINE AND COLUMN OF DATA BEING DISPLAYED IN ADDITION TO ERASING THE SCREEN. THESE COMPILERS DO NOT NEED CONTROL CODES INSERTED INTO THE WORKING-STORAGE SCREEN DEFINITIONS. SOME COBOL COMPILERS REQUIRE "ANSI.SYS" CONTROL CODES TO BE INSERTED INTO THE WORKING-STORAGE SCREEN DEFINITIONS. THE SDCOBOL "ANSI.SYS" OPTION WILL GENER ATE THESE CONTROL CODES. THE "NCR 796-101" OPTION WILL CREATE SCREEN CONTROL CODES FOR THE SCREEN IN SDCOBOL. SINCE THE SEND AND RECEIVE INSTRUCTIONS IN NCR VRX COBOL HAS NO BUILT IN CURSOR CONTROL FUNCTIONS, THIS FEATURE IS VERY USEFUL. SDCOBOL ONLY GENERATES ERASE SCREEN AND BEGINNING OF LINE CONTROL CODES. THE AUTHOR HAS WRITTEN MANY ONLINE PROGRAMS AND HAS FOUND THAT DISPLAYING/SENDING EITHER THE COMPLETE SCREEN OR A LINE AT A TIME WORKS WELL. SOURCE CODE RECORD SIZE CTRL F2 ------------------------------- HOLDING DOWN THE CTRL KEY AND PRESSING THE <F2> WILL TOGGLE THE COBOL SOURCE CODE RECORD SIZE 80 OPTION OFF AND ON. IF SOURCE COBOL RECORD SIZE EQUALS 80 IS "YES" THEN SDCOBOL WILL ADD TRAILING SPACES TO EACH SOURCE CODE LINE SO THE RECORD SIZE IS ALWAYS 80 CHARACTERS. IF SOURCE CODE RECORD SIZE 80 OPTION IS "NO " THEN EACH RECORD WILL NOT HAVE ANY TRAILING SPACES ADDED, AND THE RECORD SIZE WILL ALWAYS BE LESS THAN 73 CHARACTERS. IF "SDCOM" PROGRAM IS BEING USED TO UPLOAD THE COBOL SOURCE CODE INTO A MAINFRAME, AND THE RECORDS PER SDCOM UPLOAD BLOCK IS GREATER THAN 1 THEN SDCOM WILL ADD TRAILING SPACES TO EACH RECORD AT UPLOAD TIME SO EACH RECORD IS ALWAYS 80 CHARACTERS. SEE RECORDS PER SDCOM UPLOAD BLOCK DESCRIPTION BELOW. COMMUNICATION UPLOAD PROGRAM TO CALL CTRL F3 -------------------------------------------- THE <CTRL F3> FUNCTION KEY ALLOWS THE USER TO ENTER A PC COMMUNICATION PROGRAM TO CALL FROM THE SDCOBOL PROGRAM. THIS ALLOWS THE USER TO IMMEDIATELY UPLOAD COBOL SCREEN DEFINITIONS DURING A SDCOBOL SESSION. THE PC MUST HAVE ENOUGH RAM MEMORY FOR BOTH THE SDCOBOL PROGRAM AND THE COMMUNICATION PROGRAM TO USE THIS FEATURE. NP THE SDCOM PROGRAM INCLUDED IN THIS SCREEN DESIGN SOFTWARE CAN BE REPLACED BY MANY EXCELLENT COMMUNICATION PROGRAMS. SDCOM WAS DESIGNED TO UPLOAD COBOL SOURCE CODE TO A MAINFRAME USING THE STANDARD SOURCE CODE EDITORS SUCH AS VRX'S OLPD. IF THE USER IS GOING TO DO NUMEROUS FILE TRANSFERS BETWEEN THE MAINFRAME AND A PC THE AUTHOR RECOMMENDS THE SOFTWARE PACKAGE "ANZIO" FROM RASMUSSEN AND ASSOCIATES, 4838 SW HAMILTON CT., PORTLAND, OREGON 97221, PHONE 503-244-8516. SDCOM ===== THE FOLLOWING ENTRIES CONFIGURE SDCOM PROGRAM ONLY. IF YOU ARE NOT USING SDCOM PROGRAM TO COMMUNICATE WITH A MAINFRAME, THEN ALL FIELDS DEFINED BELOW WILL NOT BE USED. RECORDS PER SDCOM UPLOAD BLOCK CTRL F4 -------------------------------------- SDCOM ALLOWS THE USER TO UPLOAD UP TO 100 EIGHTY CHARACTER SOURCE CODE LINES AT A TIME. THIS FEATURE WAS DESIGNED FOR NCR'S VRX OPERATING SYSTEM. NCR'S VRX COBOL RECEIVE ALLOWS THE PC TO SEND UP TO 9999 BYTES IN ONE TRANSMISSION. TRANSMITTING MORE THAN 1 RECORD AT A TIME REQUIRES A SPECIAL PROGRAM ON THE MAINFRAME TO SEPARATE THE RECORDS AND WRITE THEM TO DISK. TO UPLOAD SOURCE CODE INTO A SOURCE CODE EDITOR LIKE NCR'S OLPD THE USER SHOULD CONFIGURE SDCOBOL FOR "SOURCE CODE RECORD SIZE = 80" TO "NO", <CTRL F2>, AND "RECORDS PER SDCOM UPLOAD BLOCK" TO "1". AUTO LINE FEED AFTER CARRIAGE RETURN IN SDCOM CTRL F5 ----------------------------------------------------- ALLOWS THE USER TO CONFIGURE SDCOM TO MOVE THE CURSOR DOWN TO THE BEGINNING OF THE NEXT LINE WHEN A CARRIAGE RETURN IS RECEIVED FROM THE KEYBOARD. IF THIS OPTION IS SET TO "NO", WHEN A CARRIAGE RETURN IS ENTERED FROM THE KEYBOARD THE CURSOR IS MOVED TO COLUMN 1 OF THE SAME LINE. IF THE SCREEN TEXT IS BEING DOUBLE SPACED WHEN USING SDCOM, THIS FEATURE SHOULD BE SET TO "NO ". IF TEXT IS BEING WRITTEN OVER THE TOP OF THE PREVIOUS LINE'S DATA, THIS FEATURE NEEDS TO BE SET TO "YES". WAIT TO SEND AFTER CARRIAGE RETURN IN SDCOM CTRL F6 --------------------------------------------------- THIS FEATURE FORCES SDCOM TO WAIT FOR A CLEAR TO SEND CHARACTER FROM THE MAINFRAME AFTER A CARRIAGE RETURN IS ENTERED FROM THE KEYBOARD OR A BLOCK OF DATA SENT. MOST OF NCR'S "I SYSTEMS" USE KEYBOARD LOCK / UNLOCK PROTOCOL FOR TERMINAL COMMUNICATIONS. BY USING THE <ALT F10> DEFINED BELOW THE USER CAN SPECIFY WHICH CONTROL CODE FROM THE MAINFRAME CLEARS THE WAIT TO SEND STATUS. THE WAIT TO SEND STATUS WILL ALWAYS BE CLEARED IF A "BEL" CHARACTER (HEX 07) IS RECEIVED FROM THE MAINFRAME. PRESSING THE <F4> FUNCTION KEY IN THE SDCOM PROGRAM WILL ALSO CLEAR THE WAIT TO SEND STATUS. NCR'S "VRX SYSTEMS" DO NOT USE KEYBOARD LOCKING SO THE WAIT TO SEND STATUS AFTER CARRIAGE RETURN SHOULD NOT BE USED. NP BAUD RATE CTRL F7 ----------------- DETERMINES TRANSMISSION SPEED BETWEEN THE MAINFRAME AND THE SDCOM PROGRAM. THE BAUD RATE CAN BE FROM 1200 BAUD TO 19200 BAUD. DIVIDING THE BAUD RATE BY TEN GIVES AN ESTIMATE OF HOW MANY CHARACTERS ARE TRANSFERRED PER SECOND. IF YOU ARE USING AN IBM-XT COMPATIBLE RUNNING AT 4.77 MHZ SDCOM MAY NOT BE ABLE TO KEEP UP WHEN RECEIVING DATA FROM THE MAINFRAME. THERE ARE SEVERAL OPTIONS AVAILABLE TO CORRECT THIS PROBLEM. THE FIRST, IS TO REDUCE THE BAUD RATE AT WHICH THE PC AND MAINFRAME ARE COMMUNICATING. THE SECOND, IS TO PUT A FASTER PROCESSOR IN THE PC, SUCH AS INSTALLING A 80286 PROCESSOR CARD INTO THE PC OR REPLACING THE 8088 PROCESSOR CHIP WITH A NEC V20 PROCESSOR CHIP. THE V20 CHIP CAN BE PURCHASED FOR LESS THAN $ 15.00. THE THIRD IS TO PURCHASE A DIFFERENT COMMUNICATION PROGRAM SUCH AS "ANZIO". PARITY CTRL F8, DATA BITS CTRL F9 AND STOP BITS F10 --------------------------------------------------- THESE FIELDS DETERMINE THE FORMAT OF DATA BEING TRANSFERRED BETWEEN THE MAINFRAME AND THE PC. IF YOU ARE UNSURE OF HOW TO USE THESE PARAMETERS, REFER TO THE NCR 7900 INFORMATION MANUAL OR CONTACT YOUR NCR FE. THE 2 MOST COMMONLY FOUND SETUPS ARE: 8 DATA BITS, NO PARITY, AND 1 STOP BIT, OR 7 DATA BITS, EVEN PARITY, AND 1 STOP BIT. COM PORT ID ALT F1 ------------------ IBM PC COMPATIBLES WERE DESIGNED TO SUPPORT A RS-232 COM PORT 1 THRU COM PORT 4. GENERALLY THE COM PORT 1 IS USED UNLESS A RS-232 PRINTER OR PLOTTER IS USED. PRESSING THE <ALT F1> WILL TOGGLE SDCONFIG BETWEEN THESE TWO PORTS. KEYBOARD ECHO ALT F2 -------------------- CONTROLS WHETHER THE CHARACTERS TYPED ON THE KEYBOARD DISPLAY IMMEDIATELY ON THE SCREEN OR IF SDCOM WAITS FOR THE MAINFRAME TO ECHO THE CHARACTER BACK TO THE PC TO DISPLAY. NCR 7900 TERMINALS DISPLAY ON THE STATUS LINE 25 WHETHER THEY ARE IN "FULL" OR "HALF DUPLEX". FULL DUPLEX WAITS FOR THE MAINFRAME TO SEND THE CHARACTER BACK TO THE PC BEFORE IT IS DISPLAYED ON THE SCREEN. HALF DUPLEX DISPLAYS THE TYPED IN CHARACTERS BEFORE THEY ARE SENT TO THE MAINFRAME, AND THE MAINFRAME DOES NOT ECHO THE CHARACTER BACK TO THE PC. WHEN ENTERING TEXT IN SDCOM, IF EACH CHARACTER APPEARS TWICE ON THE SCREEN IT MEANS THAT FULL DUPLEX IS BEING USED, AND KEYBOARD ECHO SHOULD BE SET "NO". IF NO CHARACTERS APPEAR ON THE SCREEN WHEN ENTERING TEXT THE KEYBOARD ECHO SHOULD BE SET TO "YES". FILE UPLOADS ARE MUCH FASTER IF THE ECHO KEYBOARD CHARACTER OPTION IS SET TO "YES", BECAUSE SDCOM DOES NOT WAIT FOR THE CHARACTER TO BE ECHOED BACK TO THE PC BEFORE THE NEXT CHARACTER IS SENT TO THE MAINFRAME. LINE DELAY F3 ------------- THE LINE DELAY IS USED TO INCREASE THE TIME BETWEEN FILE UPLOAD TRANSMISSIONS. THE LINE DELAY TIME CAN BE SET FROM 1 TO 9 SECONDS. THE LINE DELAY ALLOWS TIME FOR THE MAINFRAME TO SWITCH FROM SEND MODE TO RECEIVE MODE. IT WILL ALSO ALLOW THE MAINFRAME TIME TO PROCESS DATA FROM THE PC'S LAST TRANSMISSION IF NO COMMUNICATION PROTOCOL IS BEING USED TO CONTROL FILE UPLOAD. NCR'S OLPD DOES NOT USE ANY PROTOCOLS TO CONTROL DATA TRANSMISSION. A LINE DELAY SHOULD BE ENTERED TO ALLOW OLPD TO PROCESS THE PREVIOUS TRANSMISSION. IF CHARACTERS ARE MISSING FROM THE BEGINNING OF UPLOADED LINE THEN THE LINE DELAY TIME NEEDS TO BE INCREASED. CHARACTER DELAY ALT F4 ---------------------- CONTROLS THE TIME BETWEEN TRANSFER OF CHARACTERS; THIS TIME DELAY VARIES DEPENDING ON THE SPEED OF THE PC'S PROCESSOR. IT GIVES THE MAINFRAME TIME TO PROCESS THE PREVIOUS CHARACTER. OLDER CLC/MLA ADAPTERS ON NCR 8500 PROCESSORS COULD NOT RECEIVE A FILE TRANSFER BLOCK OF DATA AT 9600 BAUD. IT ALSO ALLOWS THE PC TIME TO PROCESS A ECHOED CHARACTER IF USING FULL DUPLEX COMMUNICATION PROTOCOL. BACKSPACE ALT F5 ---------------- DETERMINES IF THE CODE SENT TO THE MAINFRAME BY SDCOM IS A HEXADECIMAL 08 (BS) OR A HEXADECIMAL 21 (NAK). NCR 796-101 TERMINALS USE THE HEXADECIMAL CHARACTER 21 (NAK). MODEMS REQUIRE THE BACKSPACE CHARACTER TO BE A HEXADECIMAL 08 (BS) TO WORK CORRECTLY. PRINTER ON ALT F6 AND PRINTER OFF ALT F7 ---------------------------------------- THE PRINTER ON AND PRINTER OFF CONTROL CODES DETERMINE IF THE DATA BEING RECEIVED FROM THE MAINFRAME IS SENT TO THE PC PRINTER "PRN" DEVICE. IF THERE IS A PRINTER ON CODE THEN THERE MUST ALSO BE A PRINTER OFF CODE. DATA RECEIVED AFTER THE PRINTER ON CONTROL CODE IS SENT TO THE PRINTER UNTIL THE PRINTER OFF CONTROL CODE IS RECEIVED. THE PRINTER ON AND PRINTER OFF CONTROL CODES ARE NOT DISPLAYED OR SENT TO THE PRINTER. THE NCR 796-101 AND 7900 TERMINALS USE THE HEXADECIMAL CHARACTER 12 (DC2) FOR PRINTER ON AND HEXADECIMAL CHARACTER 14 (DC4) FOR PRINTER OFF. UP TO 32,000 BYTES MAY BE SENT BETWEEN THE PRINTER ON AND PRINTER OFF CONTROL CODES. THE PRINTER ON AND PRINTER OFF CONTROL CODES CAN BE THE SAME CODE. THE FIRST CODE WOULD TURN THE PRINTER ON AND THE SECOND CODE TURNS THE PRINTER OFF. PRINTER DONE ALT F8 ------------------- THIS CODE IS SENT TO THE MAINFRAME AFTER THE PC HAS SENT THE LAST CHARACTER TO BE PRINTED TO THE PRINTER. THE PRINTER DONE CHARACTER IS NOT REQUIRED IF THE PRINTER ON/OFF FEATURE IS BEING USED. IF A PRINTER DONE CHARACTER IS DEFINED, THE PC WILL WAIT FOR THE LINE DELAY TIME PERIOD (ALT F3) BEFORE SENDING THE MAINFRAME PRINTER DONE CONTROL CODE SO THAT THE MAINFRAME HAS TIME TO SWITCH IT'S RS-232 ADAPTER INTO RECEIVE MODE. THIS TIME DELAY MAY BE REQUIRED WHEN USING PRINTERS WITH LARGE BUFFERS. UNDER NCR'S VRX OPERATING SYSTEM, THE MAINFRAME ONLY RECOGNIZES THE CARRIAGE RETURN CHARACTER (HEXADECIMAL 0D), END OF TRANSMISSION CHARACTER (HEXADECIMAL 04), AND BEL CHARACTER (HEXADECIMAL 07) AS TRANSMISSION TERMINATORS. VRX WILL NOT RELEASE DATA RECEIVED TO THE MAINFRAME PROGRAM UNTIL ONE OF THESE CODES IS RECEIVED. IF THE PRINTER DONE CODE IS NOT ONE OF THESE CHARACTERS, SDCOM WILL TRANSMIT A CARRIAGE RETURN TO THE MAINFRAME AFTER THE PRINTER DONE CODE IS SENT. THE PROGRAM RUNNING ON THE MAINFRAME CAN BE PROGRAMED TO WAIT UNTIL IT RECEIVES THE PRINTER DONE CHARACTER. BY USING THIS SOFTWARE PROTOCOL, THE MAINFRAME CAN WAIT FOR THE PC PRINTER TO FINISH BEFORE SENDING MORE DATA TO THE PC OR PRINTER. IF THE PRINTER RUNS OUT OF PAPER OR IS NOT READY WHEN DATA IS SENT TO IT BY THE MAINFRAME, NO DATA WILL BE LOST. WAIT TO SEND ALT F9 AND CLEAR TO SEND ALT F10 ---------------------------------------------- THESE TWO CODES CONTROL WHEN THE MAINFRAME IS READY TO RECEIVE DATA FROM THE PC. THE PC DOES NOT SEND ANY DATA TO THE MAINFRAME AFTER THE WAIT TO SEND CHARACTER HAS BEEN RECEIVED UNTIL THE CLEAR TO SEND CHARACTER IS RECEIVED. THE PC WILL GO INTO THE WAIT TO SEND STATUS WITHOUT RECEIVING A WAIT TO SEND CHARACTER, IF THE "ENTER WAIT TO SEND STATUS AFTER CARRIAGE RETURN" OPTION IS "YES". THE WAIT TO SEND AND CLEAR TO SEND CHARACTERS CAN BE CONFIGURED TO MATCH MANY DIFFERENT SOFTWARE HAND SHAKING PROTOCOLS. SINCE SDCOM HAS AN INTERRUPT DRIVEN 32,000 BYTE BUFFER, THE "WAIT TO SEND/CLEAR TO SEND" IS USED TO DETERMINE WHEN THE MAINFRAME IS READY TO RECEIVE DATA. XON/XOFF -------- BY SETTING THE CLEAR TO SEND CODE TO HEXADECIMAL 19 (DC3) AND WAIT TO SEND CODE TO HEXADECIMAL 17 (DC1) THE PC WILL USE THE XON/XOFF PROTOCOL TO DETERMINE WHEN IT CAN TRANSMIT TO THE MAINFRAME. ETX/ACK ------- BY SETTING THE CLEAR TO SEND CODE TO HEXADECIMAL 06 (ACK) AND THE WAIT TO SEND CODE TO HEXADECIMAL 03 (ETX) THE PC WILL WORK CORRECTLY. SETTING THE "ENTER WAIT TO SEND STATUS AFTER CARRIAGE RETURN" TO "YES" AND SETTING THE CLEAR TO SEND CODE TO HEXADECIMAL 06 (ACK) THE PC WILL WAIT FOR THE HEXADECIMAL CHARACTER 06 BEFORE SENDING DATA. NCR "I SYSTEMS" --------------- SETTING THE CLEAR TO SEND CODE TO HEXADECIMAL 02 (STX) AND WAIT TO SEND CODE TO HEXADECIMAL 04 (EOT) THE PC WILL WORK CORRECTLY WITH THE NCR "I SYSTEMS". LF/CR ----- SDCOM CAN BE CONFIGURED TO USE EITHER THE LINE FEED CONTROL CODE, HEXADECIMAL 10, OR CARRIAGE RETURN, HEXADECIMAL 0D, AS THE CLEAR TO SEND CONTROL CODE. THIS ALLOWS A SOFTWARE PROTOCOL TO BE USED WHEN THE MAINFRAME IS SENDING A LINE FEED OR CARRIAGE RETURN AFTER RECEIVING A LINE OF TEXT FROM THE PC. THE CLEAR TO SEND CONTROL CODE SHOULD NOT BE SET TO A CARRIAGE RETURN SDCOM IS IN FULL DUPLEX MODE. F10 EXIT SDCONFIG ----------------- PRESSING THE <F10> FUNCTION KEY WILL TERMINATE THE SDCONFIG PROGRAM. THE USER THEN HAS THE OPTION TO SAVE THE CHANGES MADE DURING THE SCREEN DESIGN CONFIGURATION SESSION OR NOT. NP ********************* * THE SDCOM PROGRAM * ********************* THE SDCOM PROGRAM IS A COMMUNICATION PROGRAM DESIGNED TO TRANSFER COBOL SOURCE CODE GENERATED FROM THE SDCOBOL PROGRAM TO ANOTHER COMPUTER. SDCOM EMULATES AN NCR 796-101 TERMINAL BUT IT'S PERFORMANCE IS POOR COMPARED TO OTHER COMMUNICATION PACKAGES COMMERCIALLY AVAILABLE, SUCH AS "ANZIO". SDCOM CAN BE USED AS A STANDARD TTY TYPE TERMINAL. THE FOLLOWING TABLE SHOWS NCR 796-101 FUNCTIONS PERFORMED BY THE DIFFERENT CONTROL CODES RECEIVED FROM THE MAINFRAME. ASCII DECIMAL FUNCTION ----------------------------------------------------------- BEL 7 SOUND BELL / UNLOCK KEYBOARD LF 10 LINE FEED / MOVE DOWN 1 LINE CR 13 CARRIAGE RETURN / MOVE TO COLUMN 1 FF 12 FORM FEED / ERASE SCREEN BS 08 BACKSPACE CURSOR 1 CHARACTER VT 11 MOVE CURSOR TO SPECIFIC LINE DLE 16 MOVE CURSOR TO SPECIFIC COLUMN NAK 21 BACKSPACE CURSOR 1 CHARACTER ----------------------------------------------------------- SDCOM CONFIGURATION IS DEFINED BY EXECUTING THE SDCONFIG PROGRAM. THE FOLLOWING TABLE SHOWS HOW SDCOM CAN BE CONFIGURED THRU SDCONFIG FOR SPECIFIC NCR 796-101 FUNCTIONS. REFER TO THE SDCONFIG PROGRAM DESCRIPTION ABOVE. ASCII DECIMAL FUNCTION ----------------------------------------------------------- STX 2 UNLOCK KEYBOARD EOT 4 LOCK KEYBOARD DC2 18 TURN ON PRINTER DC4 20 TURN OFF PRINTER ----------------------------------------------------------- LINE 25 STATUS LINE LINE 25 COLUMN 1 ----------------- DISPLAYS "1" IF COM PORT 1 IS BEING USED OR "2" IF COM PORT 2 IS USED. SDCOM ONLY SUPPORTS COM PORT 1 THRU 4. THE COM PORT USED IS CONFIGURED IN SDCONFIG PROGRAM. COM PORT 1 IS THE DEFAULT. LINE 25 COLUMNS 3 THRU 6 ------------------------ DISPLAYS THE BAUD RATE USED BY SDCOM, AND IS CHANGED IN SDCONFIG PROGRAM. 9600 BAUD IS THE DEFAULT. NP LINE 25 COLUMN 8 ----------------- DISPLAYS THE PARITY OPTION USED. CHANGED IN SDCONFIG, EVEN PARITY IS THE DEFAULT. THE TABLE BELOW SHOWS THE DIFFERENT PARITY OPTIONS AVAILABLE. CODE OPTION --------------------------------------------------------- E EVEN PARITY O ODD PARITY N NO PARITY (USED WITH 8 DATA BIT WORD LENGTH) M MARK PARITY S SPACE PARITY ----------------------------------------------------------- LINE 25 COLUMN 10 ----------------- DISPLAYS HOW MANY BITS PER TRANSMITTED BYTE. CHANGED IN SDCONFIG PROGRAM. MOST DATA COMMUNICATION USES EITHER 7 DATA BITS AND EVEN PARITY OR 8 DATA BITS WITH NO PARITY. LINE 25 COLUMN 12 ----------------- DISPLAYS HOW MANY STOP BITS PER TRANSMITTED BYTE. CHANGED IN SDCONFIG PROGRAM. MOST APPLICATIONS USE 1 STOP BIT. LINE 25 COLUMNS 14 THRU 20 -------------------------- DISPLAYS WHETHER THE KEYBOARD ECHO OPTION IS ON OR OFF. IF ALL CHARACTERS TYPED INTO SDCOM APPEAR TWICE, THE OPTION SHOULD BE SET TO "NO ECHO" IN SDCONFIG. IF TYPED IN CHARACTERS DO NOT APPEAR ON THE SCREEN THIS OPTION SHOULD BE SET TO "ECHO ON". "ECHO ON" IS THE DEFAULT OPTION AND IS CHANGED IN SDCONFIG. SDCOM WILL RUN MUCH FASTER IF THE "ECHO ON" OPTION IS USED BECAUSE SDCOM DOES NOT HAVE TO WAIT FOR THE MAINFRAME TO ECHO THE CHARACTERS BACK TO THE PC. LINE 25 COLUMNS 22 THRU 23 -------------------------- DISPLAY WHETHER THE LINE FEED ON CARRIAGE RETURN OPTION IS ON. IF THE COLUMNS ARE BLANK THEN THE LINE FEED OPTION IS OFF. IF "LF" IS DISPLAYED, SDCOM WILL MOVE DOWN TO THE NEXT LINE WHEN A CARRIAGE RETURN IS RECEIVED FROM THE MAINFRAME OR KEYBOARD. IF THE TEXT ON THE SCREEN APPEARS DOUBLE SPACED THEN THIS OPTION NEEDS TO BE OFF. IF SCREEN TEXT ON THE SCREEN IS WRITING OVER THE PREVIOUS LINE THIS OPTION NEEDS TO BE ON. 1 UPLOAD THRU 10 EXIT --------------------- LINE 25 COLUMNS 25 THRU 80 DISPLAYS THE HELP MENU FOR FUNCTION KEY PROCESSES EXPLAINED BELOW. NP 1 UPLOAD -------- BY PRESSING THE <F1> FUNCTION KEY, THE USER STARTS THE FILE UPLOAD / TRANSFER PROCESS. THE MAINFRAME COMPUTER SHOULD BE SET TO RECEIVE THE FILE AT THIS POINT. THE USER WILL BE PROMPTED FOR THE INFORMATION REQUIRED BY SDCOM TO PERFORM THE FILE TRANSFER. THE FIRST TRANSMISSION OF DATA RECEIVED BY THE MAINFRAME AFTER THE USER HAS ANSWERED ALL SDCOM'S PROMPTS IS THE FIRST LINE OF THE FILE TO UPLOAD. AFTER THE USER PRESSES THE <F1> FUNCTION KEY, THE USER WILL ASKED IF HE WANTS TO START THE UPLOAD PROCESS. IF THE USER RESPONSES WITH "N" THE FILE TRANSFER WILL NOT BE PERFORMED. ANSWERING "Y" WILL START THE UPLOAD PROCESS. THE USER WILL BE PROMPTED FOR THE PC FILE NAME TO UPLOAD AFTER ANSWERING "Y" TO THE START UPLOAD PROCESS PROMPT. IF SDCOM IS NOT CONFIGURED FOR RECORD LENGTH 80, AND RECORDS PER BLOCK IS 1, THE USER WILL BE ASKED IF THE LINE NUMBERS FROM THE UPLOAD FILE ARE TO BE DROPPED. IF THE USER RESPONSES WITH <Y>, SDCOM WILL REMOVE THE FIRST 6 CHARACTERS OF EACH UPLOAD LINE. THIS OPTION IS USED IF THE MAINFRAME EDITOR IS ASSIGNING THE PAGE LINE NUMBER OF THE COBOL TEXT LINES BEING TRANSFERRED FROM THE PC. SDCOM WILL NOT REMOVE THE FIRST 6 CHARACTERS OF EACH LINE IF THE RESPONSE IS "N". AFTER THE UPLOAD QUESTIONS, SDCOM WILL BEGIN THE FILE TRANSFER PROCESS. DURING THE FILE TRANSFER PROCESS, LINE 25 IS CHANGED TO THE UPLOAD HELP LINE. THE LEFT PORTION OF LINE 25 DISPLAYS PC FILE NAME BEING UPLOADED. PRESSING THE <F1> FUNCTION KEY DURING THE FILE UPLOAD WILL CAUSE SDCOM TO ASK IF THE UPLOAD PROCESS IS TO BE ABORTED. LINE 25 COLUMNS 61 THRU 72 DISPLAYS THE CURRENT SDCOM UPLOAD STATUS. WHILE DATA IS BEING TRANSFERRED THIS STATUS BLOCK WILL DISPLAY "UPLOADING". AFTER THE TRANSFER OF A BLOCK OF DATA IS COMPLETED, COLUMNS 61 THRU 72 WILL DISPLAY WHY SDCOM IS WAITING BEFORE SENDING THE NEXT BLOCK OF DATA TO THE MAINFRAME. THE FOLLOWING TABLE LISTS THE DIFFERENT WAIT OPTIONS AVAILABLE IN SDCOM. WAIT MESSAGE DESCRIPTION ----------------------------------------------------------- WAIT CR SDCOM HAS BEEN CONFIGURED TO WAIT FOR A CLEAR TO SEND CONTROL CODE FROM THE MAINFRAME. LINE DELAY X SDCOM IS WAITING X SECONDS BEFORE SENDING THE NEXT BLOCK OF DATA, ALLOWING TIME FOR THE MAINFRAME TO PROCESS THE LAST BLOCK OF DATA. WAIT XXX SDCOM HAS RECEIVED A WAIT TO SEND CONTROL CODE FROM THE MAINFRAME WITH XXX BEING THE CONTROL CODE. ----------------------------------------------------------- PRESSING THE <F4> FUNCTION KEY CLEARS SDCOM WAIT STATE SO THE NEXT BLOCK OF DATA CAN BE SENT. THE UPLOAD STATUS WILL BE CHANGED TO "CLEAR KEY" WHEN THE <F4> KEY IS PRESSED. 2 FF ---- ALLOWS THE USER TO SEND A FORM FEED, HEXADECIMAL 0C, TO THE PRINTER. HANDY WHEN USING THE PRINT SCREEN FUNCTION. 3 SAVE SCREEN ------------- ALLOWS THE USER TO SAVE LINES 1 THRU 24 OF A SCREEN TO A PC DISK FILE. THIS DISK FILE CAN BE MODIFIED BY THE SDEDIT, OR LOADED INTO A WORD PROCESSOR FOR SOFTWARE MANUALS. 4 RESET -------- CLEARS THE WAIT STATUS DISPLAYED IN COLUMNS 61 THRU 72. 10 EXIT ------- ALLOWS THE USER TO TERMINATE THE SDCOM PROGRAM.
