User Instructions

Works only for files with similar organizations and record lengths. Prompts for the two files, then shows the record and position of unequal elements in the files. No further information is available.

Programmer Instructions

Primarily useful to detect small file differences. Input specification screens are GETPARMS and can be controlled through a procedure. File differences are displayed through the ERRORx screen, which is a GETPARM of the ACKNOWLEDGE type and cannot be suppressed; therefore, the program cannot be used in a background procedure.
