Lionel,
Access to MVS Files from OMVS via "//‘your.filename.goes.here’” only works for
some commands. Pre-Allocated DD’s are not available to the OMVS thread
(usually). But you might try a stream … try
[cat | cp] "//‘your.filename.goes.here’” | cksum
I believe you can cat (copy to stdout) or cp (copy to stdout) using the
"//‘your.filename.goes.here’” format. And then Pipe it to “cksum”. In this case
I do not think you will see a major performance hit (as you are tossing out the
copy anyway). Try both and pick the best performing one.
