//Generic form validation functions.
// 
//validateInput V1.0
//
//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/5.x and NS Navigator 3.x/4.x/5.x/6.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 (@, .)
//  s = validate selection list
//	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.
//
