Are minuscule alphabetics allowed in data set names?
And it depends on whether your site has disabled ICF
catalog DSN validity checking, discussed here recently.
And it depends on what language or interface to the OS
you're using. Some languages impose restrictions beyond
those imposed by the OS, particularly if DSN validity
checking is disabled.
And even in a single language, it may depend on context.
JCL, for example, permits the '-' in a "DSN=" context,
but not in a "DCB=" reference, IIRC.
<ADVOCACY> These inconsistencies are the basis for an
argument that DSN syntax checking should be performed only
by the supervisor itself, not by the various interface
layers. </ADVOCACY>
What's your objective. It might be easier if you can use
a difference of regular expressions in a boolean expression,
e.g.
/[EMAIL PROTECTED]/ ~ S &&
/.{45}/ !~ S &&
/[EMAIL PROTECTED]/ !~ S &&
/[EMAIL PROTECTED]/ !~ S &&
/[EMAIL PROTECTED]/ !~ S
... (untested)
