LET (set variable length)

LET, in combination with the LENGTH parameter, sets variable1 in a statement to the length of variable2.

As a result, the first variable becomes a 3-digit value between 000 and 256, depending on the length of the second variable.

Syntax

 LET variable1 = LENGTH variable2

where

  • variable1 is the name of a variable or array element to receive a length value. variable1 can be a character string, a numeric variable, or an array element.
  • variable2 is the variable whose length will be assigned to variable1.

Example

The following example keeps the length of file and transaction names to 70 characters or less:

LET &LTR = LENGTH &TRNID(&K)
IF &LTR > 70 THEN GOTO LAB3
