[J3] [EXTERNAL] Re: New intrinsic XXX_PREFIX and XXX_SUFFIX procedures

[Clune, Thomas L. (GSFC-6101)]

Hi Van,

I don’t think I follow your suggestion.    How does one use an enumerator as an operation?

I've been pondering this more, and I think the way I'd like to propose
this is as a single new intrinsic. I think it could in theory be named
SCAN, as the interface would be fully distinguishable from the existing
SCAN intrinsic for character set membership search. The interface would
be:

SCAN(ARRAY, OPERATION[, IDENTITY, DIM, MASK, SEGMENT, EXCLUSIVE,
REVERSED, ORDERED])

There should be two varieties of OPERATION. One would be an enumerator of an enumeration type defined in ISO_Fortran_Env. The other would be a two-argument function provided by the user.
