A Query that works standalone but not in a f(x)

Within the function I have:

for darec in select * from purchbt where addr not like ''%STE%STE%'' and
addr not like ''%STE%STE%STE%'' and (addr similar to
''%STE[A-Z]*[0-9]+'' or addr similar to ''%STE[A-Z]*[0-9]+[A-Z]'' or
addr similar to ''%STE[A-Z]*[0-9]+[A-Z][A-Z]'') loop

and it finds no records.
Outside the function, replace '' with ', I DO get the results I expect.
Back and forth, it's reliable.

I tried putting the COUNT(*) into a var and it finds 0 w/in the function
and 59K recs as a standalone query.

Any ideas?
Thanks!
