Using logical processing

Using LCDS Print Description Language

3-11

The

criid

1

and

criid

2

are the identifiers for two CRITERIA

commands. The parentheses in this format are required.

For example, the following three commands specify that a record

should be selected (RSELECT parameter) if a particular field is

equal to a given string constant (

sc

):

NOTE:

A compiler error occurs if you attempt an AND test on

two different criteria that appear on two line ranges that do not

overlap. For example, a logic problem occurs with the ROFFSET

command if Criterion 1 is limited to line 3, and Criterion 2 is

limited to line 2. In this scenario both criteria could never be

satisfied on the same line.

Specifying the

CRITERIA

LINENUM

parameter

The LINENUM parameter of a CRITERIA command specifies

that only a subset of the data record in a report will be tested for

the user defined criteria. This subset is specified as a set of

contiguous line numbers for a logical page. If the carriage control

specification for a given record places the record within the set of

lines specified by LINENUM, the record is examined according

to the CRITERIA command. Otherwise, it is not processed.

String comparisons

String comparisons for logical processing are specified using the

CRITERIA and TABLE commands. These comparisons test for

one of the following conditions:

•

Absolute equality:

Tested by either a Change mode

CRITERIA command or by a Constant mode CRITERIA

command which references a TABLE command that does not

have a MASK parameter coded. Refer to Processing

sequence 1 in the “Commands that specify string

comparisons” figure later in this chapter.

•

Equality under a mask:

Tested when the referenced TABLE

command has a MASK parameter coded. Refer to

Processing sequence 2 in the “Commands that specify string

comparisons” figure later in this chapter.

Comparing strings for equality under a mask means that the

user has specified, for each character position of the input

data string, that the test performed is one of the following:

T1:

TABLE

CONSTANT =(

sc

);

C1:

CRITERIA

CONSTANT =(

offset

,

length

,EQ,T1);

RSELECT

TEST=(C1);
