CA Endevor/DB provides a utility, NDVRCOMP, which compares the contents of two PDS members and/or sequential files, and reports the differences between them.
NDVRCOMP accepts as input two files, which can be either PDS members or sequential files. The files can be fixed or variable length, but cannot exceed an LRECL of 256 (260 for variable-length files).
NDVRCOMP reports the differences between the two files. The first file, NDVRIN1, is assumed to be the "base" file. The second file, NDVRIN2, is assumed to be the "changed" file. NDVRCOMP reports the differences in file-2 as compared to file-1.
The files are compared line-by-line, based on the contents of particular (contiguous) characters. The range of characters included in the compare is defined in terms of a from and thru column. For example, you might want to compare two files based on the contents of positions 1-5 only.
The output from NDVRCOMP can be formatted either for file browse (without ASA characters and headings) or for hardcopy printout (including ASA characters and headers).
