You cannot debug PLT programs using Debug Tool.

You can use Debug Tool in four ways:

Single terminal mode
Debug Tool displays its screens on the same terminal as the application
Dual terminal mode
Debug Tool displays its screens on a different terminal than the one used by the application
Batch mode
Debug Tool does not have a terminal, but uses a commands file for input and writes output to a log
Remote debug mode
Debug Tool works with a debugger client to display results on a workstation

For more information about Debug Tool, see Debug Tool for z/OS User’s Guide.

Note:
If you use Debug Tool in Single terminal mode, or Dual terminal mode, the terminal which is used by Debug Tool must be a local terminal in the region where the application is running: you cannot use a terminal on a terminal-owning region to interact with Debug Tool in an application-owning region.
