in reply to Have CGI call script, display status in browser
Your question is not very clear. The preceeding comments are acurate, but I'm not sure they answer your question.
If you mean "How can a CGI program send data to another CGI program" there are a couple of ways. I think the solution you are looking for is to simply point the HTML page to the second script - this is assuming that you are trying ot run a CGI from a different server. This is probably a no-no however, simply because the original author could change that program, and your HTML page would send him/her bad data - which might actually do something.
