Problem

internal workfile (WFNAME) with IDTU appended is used

the Data Set Name gets longer than 44 Bytes after the CFT variable is resolved

Working in open mode with a generic CFTRECV define as below:

WFNAME=&NFNAME.&IDTU

FNAME=&NFNAME

Resolution

For a generic CFTRECV where the WFNAME is wanted (rename, PDS support....)

It is recommended to have the WFNAME set with &PATH.&IDTU

That combination should cover most of use cases minimizing the risk to fail in a WFNAME length longer than 44 bytes.

For a FNAME=A0000001.B0000001.C0000001.D0000001.E0000001

The &PATH value will be: A0000001.B0000001.C0000001.D0000001

So the &IDTU value can always be concatened

WFNAME=&PATH.&IDTU

WFNAME=A0000001.B0000001.C0000001.D0000001.A0000101
