Numeric flags basics

Need Help??

syphilis has asked for the wisdom of the Perl Monks concerning the following question:

Hi,

Is it the case that if a perl scalar's flags includes IOK, then the pIOK flag is also inevitably set ?
Similarly, does the presence of the NOK flag guarantee the presence of the pNOK flag ?
I'm interested to see any examples showing that the answer to either of those questions is "No".

Cheers,
Rob

The only way possible to have a scalar with IOK set and pIOK not set would be with a bug. Or with an XS module with a bug.	[reply]

My follow-up (foolo'-up ?) questions would be: 1) Presumably, the same applies to the NOK/pNOK flags ? 2) Is this explicitly stated in (or implicit in) some piece of perl documentation ? In any case, I regard my initial post as having been satisfactorily answered ;-) Thanks again. Cheers, Rob	[reply]
