RE: Help me with my homework--I mean this subprocedure

The problem with this idea is that you're required to have one for each field you need to do this to.

Where as with Mike's procedure, you write it once and then just:

Pfld1 = GetPrintVal(Ffld1:%len(pfld1):%decpos(pfld1));
Pfld2 = GetPrintVal(Ffld2:%len(pfld2):%decpos(pfld2));
Pfld3 = GetPrintVal(Ffld3:%len(pfld3):%decpos(pfld3));

For the math-challenged (assuming externally described printer file):

d pfldRange ds qualified
d min like( pfld ) inz( *loval )
d max like( pfld ) inz( *hival )

if val < pfldRange.min ;
pfld = pfldRange.min ;
elseif pval > pfldRange.max ;
pfld = pfldRange.max ;
else
pfld = pval ;
endif;

No fancy math required. If pfld is set in many places,
enclose in a procedure. Also has the advantage of automatic
adaptability
(compile-time) to changes to the width of pfld; no coding of
magic numbers that need to be kept in sync with the printer
file field size.
