( #3333=superdoc: print w/ replies, xml ) Need Help??

Unfortunately it is not set to a value other than zero when the globbing produced no result

No matches is not an error. You could check for that condition explicitely.

if (GLOB_ERROR || !@list) { ... error or no match ... }

But then, why is it reset with $pat4 in the above example??

The value of $! is meaningless on success. It could be zero, non-zero, undef, etc.
