BYTELEN

The BYTELEN function will return the length of the expression as the number of bytes rather than the number of characters.

COMMAND SYNTAX

    BYTELEN(expression)

SYNTAX ELEMENTS

The expression is to be a string. The BYTELEN function will then return the byte count of the expression.

EXAMPLE

       V.UTF = 'ABCDEF' \
             : CHAR(353) : CHAR(352) : CHAR(269) : CHAR(268) : CHAR(263) \
             : CHAR(262) : CHAR(382) : CHAR(381) : CHAR(273) : CHAR(272)
       V.LEN = LEN(V.UTF)  ;  CRT V.LEN  ;* 16
       CRT BYTELEN(V.UTF)                ;* 26
    *
    * [] takes characters, not bytes, so output is:
    * 41 42 43 44 45 46 C5A1 C5A0 C48D C48C C487 C486 C5BE C5BD C491 C490
       FOR V.I = 1 TO V.LEN
          CRT FMT(V.UTF[V.I,1], 'MX') : ' ' :
       NEXT V.I

NOTES

The BYTELEN function will always return the actual byte count for the expression; irrespective of the International Mode in operation at the time. This compares with the LEN function, which will return a character count. The character count may differ from the byte count when processing in International Mode.
