// Generate the syntatic validation for interfaces built by buildForm.
//
// This was written as part of the writing of an article for the
// OpenVMS Technical Journal.
//
// This program should be run BEFORE buildForm is run as buildForm checks
// for the existance of a validation file.  This allows you to build forms
// without any validation if desired.
//
// My thanks to Chris Sands, the Director of IT at the Florida Democratic
// Party, for permission to submit this program for general use.
