DEBUGGER

2 ways to invoke the debugger:

1. launching debugger once a program is called and reaching a specific line number:

Launch a “Break” command (or  Shift + Backspace if break is de-activated) then: B <space> line nb , program name‘ The line number should correspond to an instruction line (not a comment!). The debugger has then recorded this process stop. Strike ‘”C”‘ to continue & quit the debugger. Execute all required actions in T24, if the specified program is called and pass though the line number indicated, debugger will be prompted.

Example :

 B 127,MM.MONEY.MARKET

will invoke the debugger in the  “MM.MONEY.MARKET” the program and will stop on line 127.

1. adding “DEBUG” directly in a program.

Useful Instructions keys:

P : set the source path; useful when line numbers are different between debug/source. Example: “P BPT”

S : go to next instruction. s : go to next instruction, + enter in all CALL / GOSUB.

C : finish the program execution.

V : <variable> : display a variable content.

V -M : <variable> : allows to dynamically assign a value to a variable (debugger will prompt for a value).

W : show where you are in the program (current line +/- 5 lines).

J -G : show all program context

B : display all break points. You can add a new breakpoint during the debug itself.

D delete all break points set (or to get out from a loop).
Delimiter displayed:

“delim. type” is returned for example by “REMOVE var FROM array SETTING delim. type”
