Program Storage Areas

The fifth line from the top of the breakpoint screen gives the address of various program storage areas, depending on the language of the program. For COBOL programs the line displays the address of the DSA (Dynamic Storage Area) if the program was compiled using COBOL for MVS, COBOL for OS/390, or COBOL for z/OS, the address of the TGT, the address of Working-Storage, and the address of Local-Storage, if applicable.

• The DSA address shown is the address of the Dynamic Storage Area for the current iteration of the program. To display the area, enter the command: CORE=DSA.
• The TGT address shown is the address of the storage area that contains the copy of the COBOL Task Global Table for this task. To display the area, enter the command: CORE=TGT.
• The CWK address shown is the address of the storage area that contains the copy of the COBOL WORKING‑STORAGE for this task. To display the area, enter the command: CORE=CWK.

Important! Macro-level COBOL programs operate on one WORKING‑STORAGE area that is common to all tasks.

• The LCL address shown is the address of LOCAL-STORAGE for the current iteration of the COBOL program. To display the area, enter the command CORE=LCL.
• For PL/I programs, the line displays the address of the program's DSA, while for Assembler programs, it displays the address of the program's work area.
