RE: strtok and consecutive delimiters -- RPG400-L

You get the data between the commas returned to you by strtok.
Strtok replaces the delimiter with a hex X'00' so you're right it does "eat"
the delimiters. But it does not eat the data between them.
Perhaps you have both commas and blanks in your delimiter field.

The Function eats the delimiters, I must know what data was missing between
the delimiters. A PC is passing me a Comma delimited String on a data queue.
Between each comma is critical data.

Below is a copy of the procedure in a service pgm

$GetString      B                    Export

$GetString      PI          2048a   varying
 String@                    2048a   Varying Const Options(*Varsize)
 Delimiters@                  10a   Varying Const Options(*Varsize)
 - - - - - - - -
 Local Variables
 - - - - - - - -
Token@          s               *
Stringout       s           2048a   Varying
- - - - - - - - - - -
 Load Character Array
- - - - - - - - - - -
                  If        String@ = *blank
                  Eval      Token@ = StrTok(*Null : delimiters@)
                  Else
                  Eval      Token@ = StrTok(string@ : delimiters@)
                  Endif

                  If        Token@  = *Null
                  Eval      Stringout= *blank
                  Else
                  Eval      Stringout = %Str(Token@)
                  Endif

                  Return    Stringout

$GetString      E
