Others have already given pointers and help. I thought I should point 
out that when a diagnostic is called CZKMA, the actual filename in XXDP 
will not have the leading 'C', and in addition it will have two 
characters appended, which gives a version.

So, the normal way to refer to the diagnostic CZKMA as a file in XXDP 
would be ZKMA??
