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:
• TCODE command: This command is used either to modify a
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.
