16.6. Module names in the internal trace records

Many VTAM internal trace records include the associated module names in EBCDIC, without the first prefix and, for some types of trace records, without the sixth letter. For example, you would see TSSR for module ISTTSCSR. You can save time by scanning for these module names when you are following the logic flow through VTAM. You can sometimes isolate a VTAM problem to a specific component or module without even looking at a dump. Module names can also be determined from the ISSR field in some VIT records.
