length
Description
The length() function returns the length, in bytes, of the specified string. Note that for multiple-byte character sets, the number of bytes is not the same as the number of characters; use the charlen() function instead.
Syntax
result = length (string1);
Arguments
string1 | Required. The string for which a length value is determined. |
Return Values
result is set to the length (as an integer value) of string1.
currentuser = "John Stone"; result = length (currentuser);
In this example, result is an integer with a value of 10.
