This appendix contains the predefined data type table for the standard

ASCII character set. In protect submode of block mode, the 6530 uses

this table, along with the data type attribute selected for a particular field,

to perform data type checking on characters entered from the keyboard.

The data types (0 through 7) specify a range or category of characters as
