STRING.subString

Returns a substring from start and end positions in a given string.

Syntax

subString(
     startIndex INTEGER,
     endIndex INTEGER )
   RETURNS STRING
  1. startIndex is the starting position of the substring.
  2. endIndex is the ending position of the substring.

Usage

This method returns a substring of the current STRING variable based on start and end positions in the original string.

If the STRING variable is NULL, or when the positions are out of bounds, the method returns NULL.

Important:

When using byte length semantics, the positions are expressed in bytes, and when using char length semantics, positions are expressed in characters.

Example

MAIN
  DEFINE s STRING
  LET s = "1234567890"
  DISPLAY s.subString(5,7)
END MAIN
Output:
567
