base.StringBuffer.subString

Return the substring at the specified position.

Syntax

subString(
   startIndex INTEGER,
   endIndex INTEGER )
  RETURNS STRING
  1. startIndex is the substring to be found.
  2. endIndex is the ending position.

Usage

The subString() method returns the substring defined by the start and end positions passed as parameter.

The first character is at position 1.

Important: When using byte length semantics, the positions are expressed in bytes. When using char length semantics, the unit is characters. This is matters when using a multibyte locale such as UTF-8.

Example

MAIN
   DEFINE buf base.StringBuffer
   LET buf = base.StringBuffer.create()
   CALL buf.append("abcdefg")
   DISPLAY buf.subString(2,5) -- Shows bcde
END MAIN
