Just about anyone who has performed a conversion will use the "cv" program.
It is very good. This issue comes up later, when the programs are ready and the datafiles must be updated.
There is no switch to allow programs only or datafiles only in the "cv" program.
During a conversion process, the programs are typically converted once and the datafiles are converted multiple times during the testing phase and, finally, one last time before the LIVE date.
Suggest the ability to move ONLY PROGRAMS, ONLY DATA, or BOTH added to the options.
Also, when the default SEP=$0A$, "cv" fails to read the IOLIST.
Suggest 1050 READ RECORD (X,SIZ=1024)X$; READ DATA FROM X$,SEP=$0A$ TO IOL=0110
