I have an NM KSAM file that contains records, and I now want it to be
empty. I know that I could write a COBOL program to OPEN it OUTPUT, and
voila! I would now have an empty file. I could also purge or rename it,
and rebuild it, but sure as I do that, someone will need to change a key
or a field, and then the BUILD would have to be maintained. I would
prefer to find another, sure way to do this that is less prone to human
error. I don't see where SuprTool can do this for me, nor did I see
anything searching MPEX. The best way I came up with was to rename the
original, then FCopy it to the original name, and use FCOPY
FROM=OLDFILE;TO=(NEWFILE);NEW;SUBSET="",1,EXCLUDE
to "clone" this file. I * think * that has the disadvantage of reading
all of the records in the source file to exclude them. I would like a
better approach, if there is one.
