As an OCTAL number (one byte at a time) by preceding the number with
the % sign.
As a two or three character mnemonic such as BS or DC1 (see Appendix
B of the Workstation Configuration manual).
By entering the control characters with the up-arrow or circumflex
character preceding the character, i.e. a backspace would be an ^H.
By entering the actual ASCII character within single quotes, i.e. ’A’ would
equate to an OCTAL %101.
Each character entered, with the exception of multiple ASCII characters within
the single quote, MUST BE separated by commas. An example would be
“ESC, '&16W', %101, 'ABC', BS, 13”.
NOTE: Only one byte may be specified at a time in OCTAL, thus allowing a
maximum of OCTAL 377 which would place a 1 in columns 1-8.
