Expressions on variable watchpoints and line breakpoints only support single quotes, i.e double quotes are not supported.
Watchpoint support is only available in Visual Studio 2019.
Current hit count of breakpoints while running is not supported.
The Autos panel (variables in the current procedure) is not active in this release.
Variables of the same name which exist in multiple PL/I procedures may cause issues with the variable watchpoint functionality.
This is due to a limitation of Visual Studio being unable to determine the scope of the variable at the time the watchpoint
is set.
Only the GreaterThanEqualTo mode of HitCondition is supported in this release.
Activating debugger PL/I signal and condition handling will not be supported in the Visual Studio IDE. For a workaround,
see
Catching signals and PL/I conditions using environment variables.
