Use HOME key to get to commandline. RT_ 2. how to read the session log: RT_ - a line with a leading asterisk signifies a a response RT_ or error message; the number following it refers to the RT_ number of the source line to which it corresponds. RT_ The first such line is a copy of the source line, RT_ The second is the result of a translation of the above line RT_ after all special characters and 'call' have been removed RT_ (this prevents functions and procedures from being reexecuted). RT_ - a line without an asterisk is a rDEBUG command you RT_ entered or invoked from a menu selection. RT_ - Note, not all commands are displayed permanently in the RT_ log, instead, see the message(s) in yellow at the top of RT_ the screen. They are placed there rather than in the log RT_ because the bottom window is not the d-file. RT_ 3. how to read d-file. RT_ - the first line contains several special clauses for RT_ rDEBUG initialization. It also contains your first line. RT_ - other lines, are in two parts: a prefix control command, RT_ normally 'Call debug 1...2:' (the 2: is the label RT_ for the current line) and your original instruction line. RT_ 4. to run external commands with the Editor commandline, prefix RT_ DOS to them. RT_ 5. to redo last instruction (trace's '='); use go x (where RT_ x=line number of instruction line to repeat) RT_ 6. to get last command entered press ctrl-up, however, just RT_ ignore the 'NOMSG MSG' prefix. RT_ 7. If rDEBUG should fail and your source has not been saved, RT_ you still may do so by invoking RDBEND in the commandline RT_ of the d-file. RT_ 8. on new programs, carry out the following preliminary steps: RT_ - run Indent (pretty printer) - (ALT-t,i) RT_ - run match delimiters - (ALT-t,m) RT_ - run cross reference - (ALT-t,x) RT_ - run syntax (recognizer) - (ALT-t,y) RT_ 9. use editted portions of the session logs as a means of RT_ reporting errors. Also make notes to yourself on further RT_ testing that may be required and avenues for research. RT_ 10. define all variables before referencing them. RT_ 11. you may turn off display of initial screens by changing RT_ line 2 "dbscreens=1" to 0 in file rdbINIT.kex. RT_ RT_ Related topics RT_ d-file RT_ prefix control command ET_Editor tutorial ET_ ET_ While a knowledge of Editor is not required to run rDEBUG it will ET_ help to know some of the following useful Editor commands, You ET_ must enter at least the capitalized letters of each command. ET_ Caution, at the present time, you may not enter multiple ET_ commands because the 'linend' character is not supported. ET_ ET_ <HOME> - returns you to the commandline (where ====> is) after ET_ working in file area. You must be in the commandline to ET_ enter any of the following commands: ET_ /string - causes the Editor to make the next line containing ET_ string the current line. ET_ :no - causes the Editor to make line 'no' the current line ET_ which is in the center of the d-file screen and the bottom ET_ line of the session.log and is highlighted. ET_ ALL [target] - causes only lines containing target to display, ET_ To restore normal display use 'ALL' with no target. ET_ Change /string1/string2/ [target [n [m]]] - causes search ET_ of all occurrences of string1 and replaces then with ET_ string2 from current line to nth line and for m ET_ occurrences. ET_ DIR {filespec...] - is similar to OS/2 DIR command but displays ET_ output in a file, where you can select a file with ALT-X ET_ DOS [command]: use it as a prefix to execute an external ET_ command ET_ DUPlicate [n] - copy the next n lines ET_ FFile [fileid]: unconditionally save and quit current file ET_ optionally giving it the name fileid. ET_ [Locate] target - to make the next line containing target the ET_ current line, e.g. /abc/ ET_ QQuit - unconditionally quit current file ET_ SSave [fileid] - to save the current file and optionally ET_ giving it the name fileid. ET_ Xedit [fileid] - use to begin editting another file. ET_ special shortcut keys - because rDEBUG uses ALT as a prefix, you ET_ may use CTRL to access most KEDIT ALT combinations, except ET_ copy block (ALT-C) which would become CTRL-C which is used by ET_ signal on HALT. ET_ ET_ Related topics ET_ Editor ET_ prefix control command GL_ GLOSSARY GL_ GL_breakpoint GL_ a line in your program where execution is halted because: GL_ 1. an exit statement has been encountered. GL_ 2. upon leaving the source program, a breakpoint is GL_ automatically given so that the program can GL_ be re-executed if you so desire. GL_ 3. you have set a breakpoint GL_ 4. the nth line has been executed. GL_ 5. a variable, you designate, changes value or a specified GL_ condition has been met. GL_ 6. you press CTRL-BREAK. GL_ GL_commandline GL_ an area following the arrow at the bottom of each window GL_ where you may optionally enter text-based commands to GL_ control rDEBUG and the Editor. GL_ GL_d-file GL_ a special macro file that contains a copy of your source GL_ program or macro; has calls to rDEBUG routines appended to GL_ most lines and has the debugging routines added to the end GL_ of the file. Note, the d-file displayed does not contain GL_ the debugging routines. However, the d-file stored in the GL_ current directory and the file that is being executed in GL_ memory, do have them. GL_ GL_Editor GL_ a text-based editor (KEDIT on the PC and XEDIT on VM/CMS) GL_ that rDEBUG uses to access REXX. GL_ GL_host system GL_ is the operating system under which rDEBUG will run, either GL_ OS/2, DOS or VM/CMS. GL_ GL_prefix control commands GL_ are calls to the debugging routines contained in the d-file GL_ GL_profile GL_ a file, unique to each program or macro that you are GL_ debugging, that contains the current values for configuration GL_ switches or options and the location of each prefix control GL_ command within the d-file. GL_ GL_source GL_ your program or macro to be debugged which is also contained in GL_ the d-file. GL_ GL_stepping GL_ the process of telling rDEBUG how to trace each line of your GL_ program. F8 directs to execute and trace one line, F10 does GL_ the same except all calls to subroutines are done in one step. GL_ GL_watchpoint GL_ an event that causes a break in the execution of your program GL_ There are two such events: GL_ 1. whenever a named variable changes value and GL_ 2. when a specified condition evaluates to true, e.g. (n>10).

HWA_ Note, conditional watches should not contain spaces within HWA_ the parenthesis. HWA_ HWD_DISCARD Command HWD_ <var <..var>> HWD_ HWD_ use to remove WATCH variable(s) or condition(s) from the WATCH HWD_ table and thus prevent further breakpoints from occurring when HWD_ they change.

Hitting ENTER is equivalent to GO. Note, BRG_ branching is not allowed within DO or SELECT to END ranges BRG_ because a signal command terminates such constructs. Such BRG_ ranges are indicated by a level number (digit to the left BRG_ of ';' in the prefix side of the screen) greater than zero. BRG_ BRN_NEXT Command BRN_ BRN_ use to position the editor to the line where processing is BRN_ to resume. BRN_ BRS_SHOW Command BRS_ BRS_ use with F1 key to display value for a variable at the cursor. BTP_PROFILER Command BTP_ use to display the execution counts for most lines in the BTP_ source program (this feature may be used to check if all BTP_ code has been exercised). BTF_FILES Command BTF_ use to show the status information on all files in the BTF_ current editting session. BTI_INDENTATION Command BTI_ use to indent the REXX code of the source program on disk BTI_ in a structured fashion. BTS_STRUCTURE Command BTS_ use to show only the REXX lines in the source program that BTS_ contain REXX control key words like IF and SELECT. BTW_SWITCHES Command BTW_ use to display the values of all switches and all BTW_ prefix control variables. BTY_SYNTAX Command BTY_ use to check the source program on disk for proper syntax of BTY_ all REXX commands, keywords and function calls. BTW_WATCH Command BTW_ use to display all WATCH variables and their current values. BTX_XREF Command BTX_ use to generate a cross reference map of all variables and BTX_ labels in the source program on the disk. HWS_Show Watch Command HWS_ Use to display the current value of a variable.
