/ OS/8 BOO DECODING PROGRAM / LAST EDIT: 22-OCT-1991 12:00:00 CJL / MAY BE ASSEMBLED WITH '/F' SWITCH SET. / PROGRAM TO DECODE OS/8 FILES FROM "PRINTABLE" ASCII (".BOO") FORMAT TO / BINARY-IMAGE FORMAT. INTERMEDIATE "ASCII" CONVERSION SHOULD BE HARMLESS AS / LONG AS ALL PRINTING DATA CHARACTERS ARE NOT MODIFIED. / DISTRIBUTED BY CUCCA AS "K12DEB.PAL" AS PART OF THE CUCCA KERMIT-12 PACKAGE. / WRITTEN BY: / CHARLES LASNER (CJL) / CLA SYSTEMS / 72-55 METROPOLITAN AVENUE / MIDDLE VILLAGE, NEW YORK 11379-2107 / (718) 894-6499 / USAGE: / THIS PROGRAM OPERATES ON "PRINTABLE" ASCII FILES WHICH HAVE BEEN CREATED BY / ENCODING THE CONTENTS OF ARBITRARY (BINARY) FILES. THE ENCODING FORMAT ALLOWS / FOR CERTAIN "WHITE SPACE" MODIFICATIONS SUCH AS LINE WIDTH REFORMATTING AS / LONG AS ALL PRINTING CHARACTERS ARE UNMODIFIED. EXTRANEOUS <CR>/<LF> PAIRS / AND ALL OTHER CONTROL CHARACTERS (<FF>, <VT>, ETC.) ARE IGNORED. / WHEN CREATING THE DESCENDANT DECODED FILE, THE USER MAY SPECIFY EITHER THE / IMBEDDED FILENAME OR AN ALTERNATE FILENAME ON EITHER THE DEFAULT (DSK:) DEVICE / OR A SPECIFIED DEVICE: / .RUN DEV DEBOO INVOKE PROGRAM. / *INPUT INPUT IS DECODED INTO IMBEDDED NAME ON DSK: (DEFAULT). / *DEV:OUTPUT.EX<INPUT INPUT IS DECODED INTO OUTPUT.EX ON DEVICE DEV:. / *DEV:<INPUT INPUT IS DECODED INTO IMBEDDED NAME ON DEVICE DEV:. / *OUTPUT.EX<INPUT$ INPUT IS DECODED INTO OUTPUT.EX ON DSK: (DEFAULT). / THE <ESC> CHARACTER WAS USED TO TERMINATE THE LINE / (THIS IS SIGNIFIED BY $). THIS CAUSES PROGRAM EXIT. / . PROGRAM EXITS NORMALLY. / INPUT FILE ASSUMES .BO EXTENSION; THERE IS NO ASSUMED OUTPUT EXTENSION. / PROGRAM EXIT IS THE NORMAL OS/8 METHOD OF EITHER PRESSING <^C> ON THE CONSOLE / KEYBOARD DURING THE COMMAND, OR ENDING THE COMMAND INPUT LINE WITH AN <ESC> / CHARACTER. / .BOO FORMAT IMPLEMENTATION DESCRIPTION. / THIS PROGRAM SUPPORTS STANDARD .BOO FORMAT ENCODED FILES AND OPTIONALLY THE / USE OF LENGTH CORRECTION BYTES AT THE FILE'S END TO ENSURE PROPER LENGTH. IF / NO LENGTH CORRECTION FIELDS ARE FOUND, IT IS ASSUMED THEY AREN'T NEEDED; IT / IS THE RESPONIBILITY OF THE ENCODER TO INSERT THESE FIELDS IF NECESSARY. OS/8 / FILES PROPERLY ENCODED BY THE COMPANION ENBOO-ING PROGRAM (ENBOO AKA K12ENB) / WILL CONTAIN SUCH BYTES AS NECESSARY, AND WILL BE PROPERLY DECODED INTO THEIR / ORIGINAL FORM WITHOUT LOSS. ALL OTHER FILES WILL BE <NUL>-PADDED AS NECESSARY / TO ROUND-UP THE FILE SIZE TO A NUMBER OF COMPLETE OS/8 RECORDS; THEIR / ORIGINAL LENGTH WILL BE LOST. / **** WARNING **** USE OF ENBOO-ING PROGRAMS NOT COMPATIBLE WITH THE OPTIONAL / LENGTH CORRECTION SCHEME CAN PRODUCE FILES DRASTICALLY DIFFERENT FROM THE / ORIGINAL; AN ENTIRE OS/8 RECORD CONTAINING <NUL> CHARACTERS COULD BE APPENDED / TO THE END OF THE FILES. BEYOND THE WASTE OF DISK SPACE, THESE DEFECTIVE / FILES COULD ACTUALLY BE DANGEROUS TO USE UNDER OS/8. / ORDINARILY THESE FILES SHOULDN'T EXIST, BUT COULD BE CREATED BY METHODS SUCH / AS DECODING ON OTHER SYSTEMS FOLLOWED BY USE OF ENCODERS INCOMPATIBLE WITH THE / LENGTH CORRECTION SCHEME. THIS TENDS TO MAKE THE FILE SIZE WRONG BY ONE OR / TWO BYTES, WHICH WHEN DECODED HERE WILL CAUSE THE CREATION OF AN ENTIRE / ERRONEOUS RECORD. IT IS RECOMMENDED THAT FILES STORED ON OTHER SYSTEMS FOR / EVENTUALLY DELIVERY TO OS/8 SYSTEMS BE MAINTAINED IN .BOO FORMAT TO PREVENT / THIS FORM OF FILE CORRUPTION. / ERROR MESSAGES. / ANY MESSAGE PRINTED IS A FATAL ERROR MESSAGE. ALL MESSAGES ARE THE STANDARD / OS/8 "USER" ERROR MESSAGES OF THE FORM: USER ERROR X AT AAAAA WHERE X IS THE / ERROR NUMBER AND AAAAA IS THE PROGRAM ADDRESS WHERE THE ERROR WAS DETECTED. / THE FOLLOWING USER ERRORS ARE DEFINED: / ERROR NUMBER PROBABLE CAUSE / 0 TOO MANY OUTPUT FILES. / 1 NO INPUT FILE OR TOO MANY INPUT FILES. / 2 IMBEDDED OUTPUT FILENAME FORMAT ERROR. / 3 I/O ERROR WHILE LOCATING IMBEDDED OUTPUT FILENAME. / 4 ERROR WHILE FETCHING FILE HANDLER. / 5 ERROR WHILE ATTEMPTING TO ENTER OUTPUT FILE. / 6 OUTPUT FILE LARGER THAN AVAILABLE FILE SPACE. / 7 ERROR WHILE CLOSING THE OUTPUT FILE. / 8 I/O ERROR WHILE DECODING FILE DATA OR BAD DATA. / 9 OUTPUT ERROR WHILE DECODING FILE DATA. / ASSEMBLY INSTRUCTIONS. / IT IS ASSUMED THE SOURCE FILE K12DEB.PAL HAS BEEN MOVED AND RENAMED TO / DSK:DEBOO.PA. / .PAL DEBOO<DEBOO/E/F ASSEMBLE SOURCE PROGRAM / .LOAD DEBOO LOAD THE BINARY FILE / .SAVE DEV DEBOO=0 SAVE THE CORE-IMAGE FILE / DEFINITIONS.
