RE: CGI Programming -- RPG400-L


Does the Query_String variable is created automatically by the CGI program
Or do i have to add by using ADDENVVAR command??. How do i create a
variable???.

When would we use these commands ADDENVVAR, CHGENVVAR,WRKENVVAR.???.

Sorry to ask such dumb questions.

Thanks.
Gade.

Nothing special to do.  Just use the GetEnv API and pass it the name of the
environment variable you want to retrieve.  In this case I'm guessing
you're
just pulling QUERY_STRING environment variables.  That's pretty simple.
I've got a wrapper for this API that makes it pretty easy to use as well to
retrieve any environment variable.  LEt me know if you want a sample.

An even easier way is with the QzhbCGIParse API.  It's intimidating at
first, but once you get it going, it's not bad.

I just finished writing a pretty cool wrapper for this API.  So to get QS
env. vars, all I do is.

Variable = #CGIParse('-value field')

and the data is retrieved.  If the variable should be numeric, I use my
Char
to Numeric subprocedure.  You can also use this for standard input, but it
involves two steps..

1.  use the -init command to retrieve the standard input into query string
variables.
2.  use the PutEnv to put this data to query string env. var.
3.  use -value command to retrieve the values as if it were QS data.

Works slick.  I plan on doing an article on it for MC, but if anyone wants
the code, let me know.
