Masked

comparisons

using nondefault

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 following:

set of standard default type assignments or to define a
completely new set (shown in processing sequence 3 in the
following figure).

TCODE parameter of the VOLUME command: This
parameter is used to specify the set of assignments 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 unmodified
defaults, explained in the previous section.
