MVS has a set of macros to use to dump registers and storage.
The main macro is snap.   It should be used in conjunction with
OPEN ... SNAP... CLOSE.  There must be a DCB to define the file, and
A JCL DD statement or a TSO allocate to define the snap file.


	OPEN (SNAP,OUTPUT)
	SNAP DBC=SNAP,id=001,pdata=(PSW,REGS),             X
	     STORAGE=(Start,end)
	CLOSE (SNAP)
NAP	DBC  DDNAME=SNAPPRT,LRECL=125,BLKSIZE=882,         X
	     DSORG=PS,MACRF=(W),RECFM=VBA

//SNAPPRT   dd sysout=X
