Intra-Module trace table

The intra-module trace table begins with the characters INTRA and contains the last 20 trace points encountered within modules. Each module has trace points placed at key locations, for example, at the start of procedures and around calls to other modules.

The IDs of the trace points consist of 4 characters: the first 2 characters are the mnemonic identifier of the module being traced, and the last 2 characters identify a specific point within the module. The expansion of the UTRACE macro for trace ID DLLC appears as follows:

OLDERID2 = NEWERID2;
NEWID2 = 'DLLC';
