This article will describe where to find the record layouts for the OPSLOG archives.
Where is the record layout for the OPSLOG archives documented?
OPS/MVS 12.x and 13.x
z/OS operating system
Record DSECTS can be found in **.CCLXASM(OPAR) file, with the notation that the DSECTS may have since changed. Instead we encourage use of the OPSLOG function which is documented in the "Commands and Function" manual under the "OPS/REXX Built-in Functions" section.
The OPSLOG function documentation: https://docops.ca.com/ca-opsmvs/13/en/reference-information/command-and-function-reference/ops-rexx-built-in-functions/opslog-function
