Take the information from the form and create a PHP, PERL or ASP

Not sure if you are up to this point yet,
but a <keyw id=0/> processor would go far to getting this form IDE software widely accepted.
Once a form is completed you can have another section to take the information from the form and create a PHP, PERL or ASP script that will send the information from the form. I know that there are programs out there that do this (Forms2Go) but they don't have a forms IDE (although AppNitro does) - Just a program to parse form information and create scripts from that. This would truly make this software a proper forms IDE. Regards, Troy
