300, inclusive.
Table Check The value entered must be in (or not in) a table of values.
For example, IN 5,10,15,F7+5 means the value must be
5, 10, 15, or the current value of field F7 plus 5.
Pattern Check The value entered must match a particular pattern. For
example, MATCH Aaa-ddd means the value must start with
the letter "A" and be followed by two alphabetic letters, a
hyphen, and three digits.
Check Digit A check digit in the entered value is checked according to
modulus 10 or 11. For example, CDIGIT 10 checks the
value according to a modulus 10 check digit test.

advanced processing specifications.

user enters a value greater than 10,000, a special next form, FORM2, appears when the
user presses
Enter.
