If you do not specify a SNAP option, *SNAP produces a SNAP that includes the module maps, allocated storage map, user's server, KOMM, disk buffers containing Model 204 file pages held by the current user (maximum of 4), file directory of current file, and patch information.
Syntax notes
The options can be added together. For example, to output the disk buffers for Table B and the record and resource locking data structures:
*SNAP 66 (or *SNAP X'42')
Usage notes
The *SNAP command causes Model 204 to generate a formatted dump. Issue *SNAP only for debugging purposes when requested by Technical Support.
*SNAP accepts MSGCTL SNAPSEL options. This allows you to specify a number of different types of *SNAP dumps on the *SNAP command line.
