The ED (edit) and EDMK (edit and mark) 370 instructions select
three ebcdic non-graphic codes to control the instruction operation,
leaving the remaining ebcdic codes as "message characters". Since the
codes are 0x20, 0x21, and 0x22 (ascii space, exclamation, double quote),
these instructions are not useful when the character set is ascii.
