RE: %TRIMR

[Hans Boldt <boldt@xxxxxxxxxx>]

%LEN returns the number of characters including blanks.  To get number
of chars excluding leading and trailing blanks, use %LEN(%TRIM(str)).

%SIZE(%TRIM(str)) is not allowed, since %SIZE requires a variable name
as the argument.  %SIZE returns number of bytes occupied by the variable.

You're right.  I was thinking of %size.

But will this return the number of characters?  Or will it return the
number of characters from the first non-blank to the last non blank?  In
this case the space after the comma is what I am asking about.
'Toronto, Canada'

Will this be 14 or 15?  I'm guessing 14.  Would %size(%trim($char))
return the real value he was looking for?

 Brad,

 Actually on character fields %LEN will return the number of
characters, not
 the field size. To get the field size you need to use %SIZE.

  [Stone, Brad V (TC)]  This won't work.  %len($work) will
return
 the length of the field, not how many characters there are.
CHECK and
 CHECKR should be used to get the starting and ending character
 posistions, and then uses these to get the start posistion.
