FORMULA LANGUAGE

Examples: @ValidateInternetAddress
You have designed a form asking the user to input an Internet address. The user enters a standard RFC 821 format Internet address SStreitfeld@gazette.com in the editable field User_Address.

If you enter the field validation formula

validateAddress := @ValidateInternetAddress([Address821]; User_Address);

@If(validateAddress != ""; @Failure(validateAddress); @Success)

the validation formula returns the NULL string indicating a successful validation.

However if you enter

"Streitfeld, Sara (Miami)" <SStreitfeld@gazette.com>

the validation formula returns the following error message:

"Invalid RFC821 syntax, no Phrase required."
