Recently I've been trying to write a REXX which can be invoked
directly in ISPF to add a new member to an existing PDS.
My plan is:Invoke the REXX------>It asks you for the existing PDS name
and the new member name which you want to add---->accomplish.
After reading some articles,I decide to use ISPF library services .
Manual says to add a member you should resort to LMMADD.
However,it also says to use LMMADD,LMPUT must be issued
first.
"The LMPUT service writes one logical record to the data set associated
with a given data ID"
But,what I want to do is just adding a member to PDS,then why I must
write a logical record to PDS first?
