VMS IDE uses Visual Studio Code built-in debugger and supports all of its features.

Features

VMS IDE Debugger
[1] VARIABLES 
Shows local variables. If the panel is collapsed, variables are not requested. When debugging, you can set variable values by double-clicking them and typing a new value.
[2] WATCH
You can add variable names (expressions) to set watchpoints:
* Expression without braces "()" - request variable value (local or global);
* Expression with empty braces "()" - enable watchpoint, for example x();
* Expression with conditional expression in braces "(when ...)" - enable watchpoint with condition, for example x(when (x<5)).
[3] CALL STACK 
Shows stack frames. Variables and expressions listed in VARIABLES and WATCH sections are relative to the selected stack frame.
[4] BREAKPOINTS 
Shows breakpoints set for the current project.
[5] DEBUG TOOLBAR 
Provides standard debugging actions. Edit field stopOnEntry in the launch.json file:
  • Set field "stopOnEntry" = true to enable stop on entry.
  • Set field "stopOnEntry" = false to disable stop on entry.
[6] EDITOR 
* Breakpoints can be toggled by clicking on the Editor margin or using F9 on the current line.
* Variable values can be seen by hovering over variables in the code.
[7] DEBUG CONSOLE 
Shows debugging output. Opens automatically as soon as debugging session starts.
