Syntax
long len( string_expr )
Description
This returns the number of characters in string_expr. For strings declared as FIXED, the total length of the string is returned. For non-fixed strings, the current length is returned. To retrieve the length of FIXED strings, excluding trailing spaces, use strip$().
Example
long lng
string var(20)
string fix(20) fixed
var = "abc"
fix = "abc"
lng = len( var ) | Returns 3
lng = len( fix ) | Returns 20
lng = len( strip$(fix) ) | Returns 3
