LEN

PET VIC-20 C64 C16 Plus/4 C128 X16

The LEN() function counts the number of characters in a string.

Function header

DECLARE FUNCTION LEN AS BYTE (arg$ AS STRING) SHARED STATIC INLINE

If the argument is a variable, the function will return the actual length of the string, rather than the length to which the variable was defined.

Examples

PRINT LEN("") : REM outputs 0
PRINT LEN("hello") : REM outputs 5
DIM a$ AS STRING * 16
a$ = "world"
PRINT LEN(a$) : REM outputs 5 (the actual length of the string)
