Match on Compile Date and Time
Specify 'Y' for Yes if you want the compile date and time of the source to be matched to the date and time in the matching CSECT in the measurement data. This feature only works with LE compliant modules.
If you use this feature in conjunction with a blank dataset name, your A04 Source Mapping Dataset List is searched for a source module with a compile date and time matching the CSECT. If one is found, it will be loaded. If matching source members are found, but none have the correct date and time stamp, you are given a Pick List of datasets and you can choose to use one of these.
If you specify 'N' for No in conjunction with a blank dataset name, the first instance of a matching source member in your A04 Source Mapping Dataset List is loaded, regardless of its date and time.
The behavior of this setting applies only to non C/C++ Source Map datasets. For C/C++, the field is ignored. C/C++ source mapping always requires a date/time match.
