Using logical processing • A specific print line range is specified by the LINENUM parameter, and the line or lines that are being tested contain no record (that is, the lines have been skipped or spaced over). If the test specifies a change mode function, the CRITERIA command fails because no change has occurred. However, the value for the LAST option of the CHANGE parameter remains unchanged for comparison with the next record. Test expression syntax The following diagram shows the syntax for a definition of the test expression for a logical processing command. The test definition is referenced in the syntax of each of the logical processing commands that follow it. TEST= criid; TEST=(criid1, AND, criid2); TEST=(criid1, OR, criid2); tabid: TABLE CONSTANT=sc; criid: CRITERIA CONSTANT=(offset, length, {EQ|NE}, table); command-keyword TEST=criid; Test expression example If only one criteria identifier is present (C1 in this case), the test is satisfied if the criterion is met. If the test is satisfied, the logical processing function is performed on the tested field. When two criteria identifiers are present, a test expression that contains OR (such as the RSELECT TEST command in the following example), the test is satisfied if either one of the two identifiers (in this case, C1 or C2) is present. T1: TABLE CONSTANT='Page 001'; C1: CRITERIA CONSTANT=(100,8,EQ,T1); C2: CRITERIA CONSTANT=(0,3,NE,LAST); RSELECT TEST=(C1,OR,C2); Using LCDS Print Description Language 3-3
