Logical processing command format
To define a logical processing command fully, you must specify one 
or two fields in the record or block to be tested. In general, a logical 
processing command has the following format:
command
 TEST = 
test-exp
;
The logical processing command tests the value of the specified test-
exp and directs the flow of processing based on the result of the test. 
The 
text-exp
 portion of the command defines a test to be performed 
on either one or two specified fields and their associated constants 
for a true or false value. The fields in the record or block are 
compared with their associated set of constants using either an equal 
(EQ) or a not equal (NE) operator. The basic element used to 
describe a test for a logical function is the CRITERIA command. 
Refer to the CRITERIA section in this chapter for more detailed 
information.
Logical processing commands with TEST parameters
The available logical processing commands with TEST parameters 
are listed below and are described separately in the following 
sections. Each individual command can be specified only once per 
job descriptor entry. If any one command is specified more than 
once, the last occurrence is used without notification of any error.
Table 7-2 lists the logical processing commands with TEST 
parameters
All of the above commands except BANNER are available for offline 
processing. BANNER, RAUX, RPAGE, ROFFSET, and RSTACK are 
available for online.
