DESCRIPTION

21       These are building blocks for the form library,  defining  fields  that
22       can  be  created  using set_fieldtype(3X).  Each provides functions for
23       field- and character-validation, according to the given datatype.
24
25   TYPE_ALNUM
26       This holds alphanumeric data.
27
28   TYPE_ALPHA
29       This holds alphabetic data.
30
31   TYPE_ENUM
32       This holds an enumerated type.
33
34   TYPE_INTEGER
35       This holds a decimal integer.
36
37   TYPE_IPV4
38       This holds an IPv4 internet address, e.g., "127.0.0.1".
39
40   TYPE_NUMERIC
41       This holds a decimal number, with optional sign and decimal point.
42
43   TYPE_REGEXP
44       This holds a regular expression.
45

PORTABILITY

47       The TYPE_IPV4 variable is an extension not provided by older  implemen‐
48       tations of the form library.
