iframes seem to be very tricky. i have 4 frames on my html page and can we set them like if 1st frame gets more data and it should expand to show all and at the same time can other 3 frames expand accordingly?
can someone post some tips when working with multiple frames on html page.

First off, why are you using iFrames for this. Do you "just" want to display four individual reports, one over the other? If so just run the four (report generating) focexecs "in line". Or, use the !IBI.FIL.filename;. Or, there's a few more depending on what output you want.

I've had the same question a couple of years ago (3 iframes and all of those iframes had to start were the "previous one" ended AND all these iframes had to have no scrollbars).
After some searching on the laptop, I found the code I used. I did a quick translate of the code, so it's maybe not the best English, but I hope you'll get the point.
The approach was:
1: Hide all IFRAMES after clicking the run button (+ show WAIT-message) 2: Wait for all IFRAME's to complete 3: Adjust height 1-by-1
That's it.
This example uses 3 fexes (car11/12 and 13); these are also copied below the HTML (I ran it all from baseapp )

That's the "!IBI.FIL.filename;" whioch I was talking about. Each of those "-HTMLFORM"s expands as required and display everything. You could even add the center tags.
-HTMLFORM BEGIN
<html>
<center>
!IBI.FIL.RPRT1;
</center>
</html>
-HTMLFORM END
to each -HTMLFORM... Why? Why Not?

You're right about expanding if the ouput is re-directed to a new window.
If the output is re-directed to iframes, those iframes are not expanded by default to fit the report and from what I understood, the output had to be in an iframe. And 4 out of 5 customers I worked for want to have a "all-in-1-screen" (parameters and output), so iframes are quite OK to work with.
