LIBRXREF: Object file or BASIC source file.

User Instructions

Produces a report showing the names, editing, level, and usage of all fields within a given COBOL file or library. This listing can be used to find field usage across many COBOL programs.

To use, enter the name of the file (or library) to be processed. The program will display the name of each file as it is processed, then produce a cross-listing of field usage by file. This report shows the program name, data name, data level, PICTURE, usage ((GR)roup, (B)inary, (I)ndexed, or (C)omputational), and any use of OCCURS or REDEFINES. If an entire library is processed, a second report lists the names of the files processed that run.

Programmer Instructions

LIBRXREF consists of a single GETPARM screen. Note that the use of the workstation to display search progress eliminates background use of the utility.

If you expect a large listing and wish to increase the allocated size of the print file, use the PRNAME PRINT to intercept the hidden output GETPARM for the report. (The default record count is only 1000.)
