Re: %trim blanks or nulls?

How much more efficient though, because the %trimL would be done processing
immediately upon finding index 1 of the string is not one of the trim
values. Are we talking 1/100th of a nano second? (obviously it is relative
to your computing power)

Yes it would be...

I %Trim() does both %TrimL() and %TrimR(). Therefore, a %TrimR() would be
more efficient.

Thanks all. Barbara's code did the trick.

If does lead me to another question on %trim, %trimr. If you know
for sure the field is left justified and you want to trim off
trailing blanks, is using %trimr more efficient than %trim? They
would both have the same results. I tend to always user %trim for

everything

Does the %trim bif look for just blanks (hex 40) or does it also trim
nulls (hex 00) I have two 15 character fields. One is coming from a
database, one is passed as a parameter. Both contain an IP address
(aaa.bbb.ccc.ddd). In the database field the trailing characters are
always spaces if the ipaddress is not the full 15 characters. The
parameter being passed will sometimes end in spaces and sometimes end
in nulls (hex '00'). I did a compare using... If %trim(dbfield) <>
%trim(parameter); And when the parameter field ended in hex 00 the if
was evaluated as true.

You can trim any combination of blanks or nulls if you use the second
parameter of %trim.

If %trimr(dbfield) <> %trimr(parameter : ' ' + x'00');

If parameter = 'a.b.c.d ' or 'a.b.c.dnnnnn' or even a mixture of
blanks an nulls like 'a.b.c.dn nn n ', the result of the second %trimr
of parameter would be 'a.b.c.d'. (where n = null)
