len() Return the length of a string
------------------------------------------------------------------------------
Declaration
string.hdr
Syntax
func uint len extern
param const char cString
Arguments
cString is a character string.
Return
Length of the input string.
Description
The len() function returns the length of cString. The length of a
string is determined by the position of the NULL character in the string
versus the declared size of the string.
Example
#define EXAMPLE_STRING
#include example.hdr
proc Test_len
vardef
char( 90 ) cString
enddef
// len() returns the length of the current value of a string, not its
// declared width
cString := "this"
? len( cString ) // prints 4
? len("Melanie Neale") // prints 13
? len("") // prints 0
? len(space(40)) // prints 40
endproc
proc main
Test_len()
endproc
