       TYPE_NUMERIC TYPE_REGEXP - form system global variables

SYNOPSIS

       #include <form.h>

       FIELDTYPE * TYPE_ALNUM;
       FIELDTYPE * TYPE_ALPHA;
       FIELDTYPE * TYPE_ENUM;
       FIELDTYPE * TYPE_INTEGER;
       FIELDTYPE * TYPE_IPV4;
       FIELDTYPE * TYPE_NUMERIC;
       FIELDTYPE * TYPE_REGEXP;

DESCRIPTION

       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 deci-
       mal point.

   TYPE_REGEXP
       This holds a regular expression.

PORTABILITY

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