Using Debug Tool with CICS applications

Debug Tool helps you test programs and examine, monitor, and control the execution of application programs.

You can debug the following sorts of CICS® applications using Debug Tool:

Applications written in a compiled language (COBOL, PL/I, C, C++)
Language Environment®-enabled Assembler subroutines
Applications that use a combination of compiled language programs and Java™ programs. Debug Tool does not debug the Java portions of these applications

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.

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.
