Will it convert to FYYMMDD?
Does it handle year boundaries correctly, or is ZJDATE simply treated
as a 5-digit integer?

Suggested here a while back was EZACFSM1:
https://listserv.ua.edu/cgi-bin/wa?A2=ind1304&L=ibm-main&P=602076
... seems to belong to TCP/IP. Will also perform substitution in instream
data sets (text is text). IIRC a while back it wouldn't substitute beyond
column72; it seems to be better now. No arithmetic capability that I
know of.
I believe Rexx will do arithmetic and format conversions on dates.
