CGI Scripts

CGI scripts have two purposes

generate the form
Forms do not have to be embedded within a document, they can be generated on-the-fly by scripts. This is true for all
documents, not just forms.

Using scripts to generate and process the form is convenient as there is more chance that both the generating and
processing end of the script will be modified at the same time, reducing the risk of them getting out of step.
On servers containing a fair amount of documents it can be sometimes difficult to remember exactly where
documents containing forms are.

If your form is going generate and process the form, it needs to know when to do each activity.
generate when the script has no arguments.
process when the script has arguments.
