Thanks to all who responded.
I have elected to use the FOR loop method as this program currently does not use SQL,

Subject: RE: Find number of times a value occurs in a field

I have a field of 31 bytes that can have the value "O" or "W".
I *thought* there was either a BIF or Op-Code that I could use to
find
the number of times a value occured, but can not find it in the
manual.
ie: if the field contained WWWWWOOWWWWWOOWWWWWOOWWWWWOOWWW,
I would like to be able to get the value 23 for the number of times
the
W occurred.

Well, I'm generally opposed to using SQL for non-SQL functions but this
one
is ripe for the taking.  :)  Besides, if I don't suggest it then
Birgitta or
Luis or Charles will.  :)

Exec SQL Set :wCount = length(trim(:field)) -
length(trim(replace(:field,'W',''))) ;

I think that would do it.  (Note lack of space between ending
apostrophes on
that replace verb.)

(There is an underlying assumption that embedded blanks will not appear
within.  With embedded blanks, the count can be overstated.  Perhaps
significantly, as when field = 'W.............................W' (where .
represents a space).
