Hi !

Yes, it's possible. You could take a so called SNAP Dump. Therfore first you have to code a special DCB in the programm.

Programm:
SNDCB DCB DSORG=PS,RECFM=VBA,BLKSIZE=882,
MACRF=(W),LRECL=125,DDNAME=SNDUMP

Then in the programm at the point of your desire, you can take a storage, register, field or whatever dump via snap macro.

mvc
mvc
SNAP DCB=SNDCB,STORAGE=(FIELD_A1,FIELD_A9)
mvc
mvc

Complete SNAP command:

SNAP DCB=SnapDcbName
ID=IdNumer
PDATA=(Field,Field...)
STORAGE=(Beginn,End)
LIST=Adress

Please look at Ass-Bookmanager for further details.

Regards & happy new year

Hi UmeySan,
Thank you very much. I am just trying to create a debugger. This will be of great use.
I am trying to produce a dump without altering the source program.
Thanks...
