PROCESSING SPECIFICATIONS FOR FIELD EDITS 

If only field editing is needed, the edit statements listed below provide
full field edits.  Edit statements apply to the current field only.
During table and range checks leading and trailing blanks are stripped.
(The current field is the field defined in the Field Menu in which the
edit statements are specified.)

Edit Statements 

The FORMSPEC edit statements allow you to check whether the value of the
current field:

 *  is at least a specified minimum length; refer to "Length Check" for
    the MINLEN command.

 *  is greater than, equal to, or less than a specified value; refer to
    "Single Value Comparisons" for the GT, GE, LT, LE, EQ, and NE
    commands.

 *  is one of a list (table) of values, or is not in the list; refer to
    "Table Checks" for the IN and NIN commands.

 *  is within a range of specified values; refer to "Range Checks" for
    the IN and NIN commands.

 *  has a valid check digit; refer to "Check Digit" for the CDIGIT
    command.

 *  matches a general pattern of characters; refer to "Pattern Match" for
    the MATCH command.

Edit statements use the set of statements listed in Table 4-1.  They are
performed in the order they are entered by the forms designer.  As soon
as an edit fails during execution, the field is marked in error and
further processing on that field is abandoned.
