The LEN function returns the number of characters in a character expression. Trailing blanks are ignored.
We define the following variables:
Variable Type
&CExp C(20)
&Length N(1)
Source:
&CExp = 'HELLO'
&Length = Len(&CExp)
&Msg = concat('LEN returns', Str(&Length,1), '')
&CExp = ' HELLO ' //(trailing blanks will be ignored)
&Length = Len(&CExp)
&Msg = Concat('LEN returns', Str(&Length,1), '')
The result is: 'LEN returns 5' and 'LEN returns 6'
