Detailed Description

Many macros in the core library accept a library.dataset parameter referred to as 'libds'. This macro validates the structure of that parameter, eg:

• 8 character libref?
• 32 character dataset?
• contains a period?

It does NOT check whether the dataset exists, or if the library is assigned.

Usage:

%put %mf_islibds(work.something)=1;
%put %mf_islibds(nolib)=0;
%put %mf_islibds(badlibref.ds)=0;
%put %mf_islibds(w.t.f)=0;

Parameters

[in]

libds

Returns
