MACROLOG
When the MACROLOG option is set, all IDF commands that are issued
by macros or exit routines are written to:
- On CMS, "ASM MACROLOG fm", where fm is specified by the MODE option (and defaults to file mode A1).
- On z/OS®, the commands are written to the data set defined by the MACROLOG DD name.
- On z/VSE®, the commands are written to the data set defined by the MACROLG DLBL.
