mode)
Missing DD card Recording mode was wrong
Bad load module (Subroutine program ID and program name not the same)

(Contd.)S0C7 - Program Check Exception Data
How to solve it? Find out the next sequential instruction to be executed from SYSUDUMP
Go to compile listing and find the instruction where the abend occurred
(HEXLOC - OFFSET)
Check for initialization of packed variables in the statement
Check for correct data present is moved to packed fields
Otherwise, go to Diagnostic Section of DUMP and find out the offset anddisplacement. This helps to locate the field in problem.
Check for spaces in a packed decimal or numeric field.
Check to see if record layouts or file layouts have been changed.

SB37 Abend:
Insufficient disk space.
SD37 Abend:
Insufficient disk space.
SE37 Abend:
Insufficient disk space.
The maximum number of extents would be exceeded.
For instance, when exceeding 16 extents of a PDS.
An E37 on tape datasets is most often caused when the number of requested
volumes is exceeded.
The default is 5, therefore a request for the sixth volume will fail with a E37.
