Re: Triming CL stings?

[Booth Martin <booth@xxxxxxxxxxxx>]

Here is an example from the manual:

*CAT (concatenation, symbol ||) operator

   The *CAT operator concatenates two character strings. For example:
   ABC *CAT DEF becomes ABCDEF

   Blanks are included in the concatenation. For example: 'ABC ' *CAT
   'DEF ' becomes 'ABC DEF '

*BCAT (concatenation with blank insertion, symbol |>) operator

   The *BCAT operator truncates all trailing blanks in the first
   character string; one blank is inserted, then the two character
   strings are concatenated. Leading blanks on the second operand are
   not truncated. For example: ABC *BCAT DEF becomes ABC DEF 'ABC '
   *BCAT DEF becomes 'ABC DEF'

*TCAT (concatenation with trailing blank truncation, symbol |<) operator

   The *TCAT operator truncates all trailing blanks in the first
   character string, then the two character strings are concatenated.
   All leading blanks on the second operand are not truncated. For
   example: ABC *TCAT DEF becomes ABCDEF 'ABC ' *TCAT DEF becomes
   'ABCDEF' ABC *TCAT ' DEF' becomes 'ABC DEF' 'ABC '*TCAT ' DEF'
   becomes 'ABC DEF'
