Can I define a ISQL or I4GL form wider than 80 columns?

The do开发者_StackOverflow中文版cos say "screen size 80 by 20" but I would like to go to 132 columns wide.

You can if the termcap or terminfo entry supports it. You 'simply' specify the size on the SCREEN line in the form.

In principle, I4GL should detect the screen size automatically, and work happily. However, there's a chance that you might need to do more than you really should - setting COLUMNS and ROWS as environment variables, for example. And don't rely on I4GL detecting changes in window size reliably (SIGWINCH).
