URL in RPG

[Jerry Adams <jerry@xxxxxxxxxxxxxxx>]

There was a thread last week regarding how to pull up a web site from 
within an RPG program.  The basic process was summarized as:


CMD        PROMPT('Launch Browser')

PARM       KWD(URL) TYPE(*CHAR) LEN(90) MIN(1) +
          EXPR(*YES) PROMPT('URL to launch')


PGM  PARM(&URL)

    DCL VAR(&CMD) TYPE(*CHAR) LEN(123)
    DCL VAR(&URL) TYPE(*CHAR) LEN(90)

    STRPCO PCTA(*NO)
    MONMSG IWS4010

    CHGVAR VAR(&CMD) +
    VALUE('rundll32 url,FileProtocolHandler ' *BCAT &URL)

    STRPCCMD PCCMD(&CMD) PAUSE(*NO)

ENDPGM


However, it keeps barfing with a Windows dialog box titled "RUNDLL" with 
the message: "Error in URL  Missing entry: FILEPROTOCOL HANDLER".I ran 
debug over it and the &URL field is initialized.


I, also, ran a sample program that Scott (I think) put up to test 
whether or not one had the necessary tools on the workstation:


PGM
        STRPCO
        MONMSG IWS4010
        STRPCCMD PCCMD('start http://www.midrange.com') +
                 PAUSE(*NO)
   ENDPGM


This worked fine. 


This seemed like such a neat idea, when I read it.  Any idea what I'm 
doing wrong?


Thanks.
