//ABOUT.
//
//These routines are called from a forms onSubmit event and test for
//appropriate data values in corresponding fields, if any of the values are
//missing or of the wrong type the user is prompted and submission halted.
//
//The actual validation functions are intentionally simple, the purpose of
//this code is to provide a generic form validation handler that will work
//in MSIE 3.0x/4.x and NS Navigator 3.x and Communicator.
//
//The handler function - validateInput() accepts two parameters, the name of
//the form to be processed and a string that provides a mask against which
//each field on the named form can be validated.
//
//This mask is the key to the functionality of this script. For each field on the form
//the corresponding character in the mask string tells the handler how to perform the
//validation.
//
//The mask string can contain the following characters;
//
// d = validate value as a date
// t = validate value as text
// n = validate value as a whole number (1234567890)
// p = validate value as a phone number (+,(), 1234567890)
// e = validate value as an e-mail address (@, .)
// u = unrequired - do not validate
//
//The function can be used to process multiple forms on a single page,
//this is useful for ASP developers who commonly generate input and
//confirmation forms within a single .asp file.
