CRITERIA command parameters
A CRITERIA command may contain only one specification of
one of these parameters: CONSTANT, CHANGE, or VALUE. In
addition, it may optionally contain the LINENUM parameter.
Thus, one or two parameters must be provided in the CRITERIA
command.
The following table summarizes the CRITERIA command
parameters and gives their uses and functions.
CRITERIA CHANGE
Defines test specifications for a logical processing function with
Change mode criteria. Specifies the length and location of a
control field in each record, to which the next record is
compared. When the content of one record differs from the
content of the control field of the previous record, the criteria test
is TRUE.
