Analyzing Reporting Facility Output › MAP Listing › Compile Diagnostics

Compile Diagnostics

The Compile Diagnostics is divided into five units:

1. The File Summary displays general information regarding both input and output files for the run, including blocking factors, record sizes, and block sizes for each file. It includes sort key information if more than one report is to be generated or a CONTROL statement is coded.
2. The General Storage Area Summary (GSA) lists each of the eight types of GSA entries added to the GSA during compilation, and the number of entries required in each category. The system also uses this area as a cross-reference to the Trace Facility.
3. The Field Names Table Summary (FNT) lists the four types of field name entries required in the run, including labels, scalar variables, internal file description blocks and arrays, and the number of entries required in each category.
4. The Function Specification Table Summary (FST) lists the 16 types of FST entries required in the run. The Reporting Facility uses FSTs internally to generate machine code to perform specific functions.
5. The Memory Use Summary displays the estimated core storage requirements for the internal compilation work areas. This does not include core storage required for the execution of the program, such as input buffers, machine code, and external software.

Following is a sample of the fourth page of the report. For an example of the report header (not shown here), see Sample Report Headers).
