DESCRIPTION         top

       These are building blocks for the form library, defining fields that
       can be created using set_fieldtype(3X).  Each provides functions for
       field- and character-validation, according to the given datatype.
   TYPE_ALNUM
       This holds alphanumeric data.
   TYPE_ALPHA
       This holds alphabetic data.
   TYPE_ENUM
       This holds an enumerated type.
   TYPE_INTEGER
       This holds a decimal integer.
   TYPE_IPV4
       This holds an IPv4 internet address, e.g., "127.0.0.1".
   TYPE_NUMERIC
       This holds a decimal number, with optional sign and decimal point.
   TYPE_REGEXP
       This holds a regular expression.

PORTABILITY         top

       The TYPE_IPV4 variable is an extension not provided by older
       implementations of the form library.
