1 – Full Description
By default, when records are sorted with identical keys, the order of those records in the output file may not be the same as they appeared in the input file. Specifying the /STABLE qualifier in a specification file arranges records with equal keys in the output file in the order of the input files as specified in the command line. If you use this qualifier when sorting multiple input files, on output, records with equal keys in the first file will precede those from the second file and so on.
2 – Example
/STABLE This example of the /STABLE qualifier ensures that records with equal keys will have the same order in the input and output files.
