PLAYBACK ENABLE command

The PLAYBACK ENABLE command informs z/OS® Debugger to begin recording the statements that you run and information about your program. If z/OS Debugger is already recording the statements that you run, you can use the PLAYBACK ENABLE command to inform z/OS Debugger to record the statements that you run in other compile units or to change the effect of the DATA option.
cuname
Name of the compile unit or compile units where z/OS Debugger is to record the statements that you run. You can specify only the names of the compile units currently known.
*
Specifies that z/OS Debugger is to record the statements that you run in all compile units. This is the default.
integer
Specifies the maximum amount of memory to use to store data that is collected. The integer value specifies a unit of K (1024) bytes. For example, an integer value of 2000 indicates 2,048,000 bytes. The default value is 8000.
DATA
Specifies that z/OS Debugger is to save information about your program, such as the value of variables and registers. z/OS Debugger saves this information for the compile units that you specify in the cuname parameter or, if you specified the * parameter, for all compile units. The DATA parameter is effective only for compile units compiled with the following compilers:
  • Enterprise COBOL for z/OS, Version 6
  • Enterprise COBOL for z/OS, Version 5
  • Enterprise COBOL for z/OS, Version 4
  • With the following compilers, you must also specify the SYM suboption of the TEST compiler option:
    • Enterprise COBOL for z/OS, Version 3.3 and Version 3.4
    • Enterprise COBOL for z/OS and OS/390®, Version 3 Release 2
    • Enterprise COBOL for z/OS and OS/390, Version 3 Release 1, with APAR PQ63235
    • COBOL for OS/390 & VM, Version 2, with APAR PQ63234
DATA is the default.
NODATA
Specifies that z/OS Debugger does not save information about your program.

Usage notes

  • For COBOL only: If you enter the PLAYBACK ENABLE DATA command, and a compile unit supports the DATA parameter, the following information is recorded:
    • FILE SECTION
    • WORKING-STORAGE SECTION
    • LOCAL-STORAGE SECTION
    • LINKAGE SECTION
    • All special registers except for: ADDRESS OF, LENGTH OF, and WHEN-COMPILED
