Masked comparisons using default type assignments
Performing masked comparisons using unmodified standard default
type assignments requires coding the following:
•TCODE command. Used either to modify a set of standard
default type assignments or to define a complet ely new set
(refer to processing sequence 3 in figure 7-1). Refer to th e
“Character type assignments” section in the chapter “Specifying
input parameters,” for detailed information on the TCODE
command.
•TCODE parameter of the VOLUME command. Allows you to
select a set of standard default type assignments .
•MASK and CONSTANT paramete rs of on e or m ore
occurrences of the TABLE command. Together, thes e
parameters define exactly how the comparisons for that TABLE
command are made using the set of type assignments specified
by the TCODE parameter of the VOLUME com mand.
Masked comparisons using non-default type assignments
Performing masked comparisons using either a nonstandard
character set or a standard set for which the default type
assignments are not suitable requires coding the follow ing:
•TCODE command. This command is used either to modify a
set of standard default type assignments or t o define a
completely new set (refer to processing sequence 3 in figure
7-1). Refer to the “Character type assignments” section in
chapter “Specifying input parameters,” for detailed information
on the TCODE command.
•TCODE parameter of the VOLUME command. This
parameter is used to specify the set of assig nments defined by
the TCODE command as the one used for masked comparison.
•The MASK and CONSTANT parameters of one or more
occurrences of the TABLE command. The use of these
parameters is the same as for comparisons using un modified
defaults.
