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.
