Space management and buffer handler module trace IDs
In space management and DL/I buffer handler trace entries, a 1-byte module ID identifies the calling module. A 1-byte subcode identifies the specific call within the module.
Space management and DL/I buffer handler trace entries
The calling module places the module ID in field PSTTRMID and the subcode in field PSTTRMSC before making the call. The DL/I buffer handler and space management then move these PST fields to the appropriate traces.
The PSTTRMSC module subcodes are 0 through 9 and A through Z. If you need to find the point in the module where the call was made, look for the TIDSCx label that corresponds to the module subcode. Subcode 0 corresponds to label TIDSC0, subcode 1 to label TIDSC1, subcode A to TIDSCA, and so on.
The following table describes the ID, the calling module, and the module function

Example of a DL/I trace
The following example shows a DL/I trace. The trace entries show two GHU calls. All calls use Program Specification Table (PST) 01. When activities for different PSTs are intermixed in the trace table, you need to examine only the entries for the PST that you are interested in.
