I checked TSAFS.nlm. Both have same version number, but TSA5UP18 is
smaller in size and dated May/June 2005 whereas TSAFS.nlm in sp4a is
dated Aug05 and is larger in size. Both are same version number.

Thus, I am having an abend in TSA process. Is TSA5UP18 newer or not.
What version should be used.
