Xerox FreeFlow manual Character to type associations, Criteria command modes

Using logical processing

Example 4 The TABLE command below sets up the character to type associations shown in the following table.

T2: TABLE		MASK=('*',':','!'),
		CONSTANT=('DATE ::/::/:: ID!!!');
	Table 3-6. Character to type associations
Mask	Mask	Character
position	character	type	Meaning
0	*	None	Make no comparison
1	:	1	Any numeric (0 through 9)
2	!	2	Any alphabetic (A through Z, a through z)

A logical test using this TABLE command examines a field of an input data record to determine if the following conditions are met:

•The word DATE is present.

•The / is in the right place.

•The date itself is numeric (type 1).

•The string ID is present.

•The first three characters after ID are alphabetic (type 2).

CRITERIA command

The CRITERIA command specifies that a test for a particular logical function will be performed on a specific field in the record. This command requires an identifier, which is specified with the TEST parameter in any of the logical processing commands. Specific TEST parameters are described in the individual logical processing command sections.

CRITERIA command modes

There are three formats or modes for CRITERIA commands: Constant mode, Change mode, and Value mode. You select the mode by specifying either the CHANGE parameter, the CONSTANT parameter, or the VALUE parameter of the CRITERIA command in your JSL.

NOTE: A command may specify only one mode. However, CRITERIA TABLES may specify either Change mode, Constant mode, or both functions; there are no restrictions on their usage or combination in tables.
