Yes, I'm reading.

Have you written a procedure for extracting numbers from a
character field?  If not, why not?  If so, when will you
make that procedure available to other RPG programmers?

Let's say we agreed that a %VALUE BIF would be useful in
the language.  Considering current schedules and
commitments, this new function won't be in the language
for, say, another two years (more or less).  And it will
be another two or three years before all of your systems
are running that release, so chances are that you wouldn't
get to use the new BIF for another five years!  But, if
you wrote a procedure now to do this, and offered it to
others, everyone could be doing this now.


Or, you could learn Perl.  To get all numbers out of a
character string, you could code that in Perl as:

     @nums = $str =~ /\d+/g;
