Using Logical Processing
Parameter
CONSTANT=
(offset,length,
EQ | NE,tab-id)
LINENUM=
(init, count)
Notes to CRITERIA
The activation of testing is done by coding the TEST parameter of any logical processing
command described in this chapter. Either one or two CRITERIA commands can be spec-
ified.
Test expression definition
The following is a definition of the test expression for a logical processing command. The
test definition is referred to in the syntax of each of the logical processing commands that
follow:
TEST=cri-id;
TEST=(cri-id
TEST=(cri-id
The cri-id
1
RIA commands discussed in this section. If only cri-id is present, the test is satisfied if the
criteria in cri-id is satisfied.
If two CRITERIA commands are specified for a test, the testing of two is linked by either an
AND or an OR logical operator.
If AND is coded, both CRITERIA commands must be true for the same data record in order

Definition(s)
offset
The offset in bytes (relative to zero) from the start of the physical tape block to a
field within the tape block being compared to a table or string constant. In the case
of record processing, it is the offset from the start of the user's portion of the record
to the field in the record being compared.
length
The length in bytes of the test field. Its range is 1 to 255
EQ | NE
Keywords that specify the operation of equal to or not equal to.
tab-id
The identifier of a TABLE command.
There is no default.
This parameter specifies the range of consecutive line numbers for which the CRI-
TERIA command is fully evaluated.
init
An integer specifying the number, on each page, of the beginning line for which the
CRITERIA command is evaluated.
count
An integer specifying the consecutive number of lines (starting with init) for which
the CRITERIA command is evaluated.
The default is all lines.
