Using logical processing3-2 Using LCDS Print Description LanguageTest expressionsTo define a logical processing command fully, you must specifyone or two fields in the record that will be tested. In general, alogical processing command has the following format:parameter command-keyword = options, ...,command-keyword TEST = testexp, ...;The testexp parameter of a logical processing command definesa test that will be performed on either one or two specified fieldsand their associated contents. The test result is a TRUE orFALSE value. The fields in the current data record are comparedwith either of the following:• One or more constants associated with the test, using eitheran EQUAL (EQ) or a NOT EQUAL (NE) operator.• The contents of the field in prior records using a NOT EQUAL(NE) operator.The basic element used to describe a test for a logical function isthe CRITERIA command.Coding a test expressionTo activate testing, you code the TEST parameter of any logicalprocessing command that has one. (For information onconstructing the TEST parameter, refer to the commanddescription, Syntax section, for the command you want to code.)Criteria identifiers(criids)In the TEST parameter, you must include one or two criteriaidentifiers (criids), which you specify in the CRITERIA command.These criid options are the identifiers of the CRITERIAcommands that specify the location of the test fields and whatthey will be compared to.Exceptions There are two special cases in which the TEST parameter doesnot function as described above, and the CRITERIA commandfails:• For offline printing: the record is too short to include thewhole field that is being tested. (For online printing, therecord is padded with blanks to make it large enough.)
