When you POINT with Z=0, CMS decrements

No;

In or out of a PDSE spanned records make LRECL BLKSIZE possible.
Attitudes toward RECFM=VBS probably reflect a mixture of 1) longevity

I have successfully used POINT, READ, and CHECK Macros on CMS to read MVS
datasets, but never had a need for NOTE.
How did you successfully use POINT without having first done a NOTE so that
the POINT knows where to POINT?
