All three formats are equivalent, so you can pick the one best suited
your
to purpose. For instance, a BASIC programmer might refer to the
first and second formats, a word processor might use the second, and a
machine code programmer would use the third format. Variables are
represented by italicized letters such as n, nl, m. The variables are
explained in the comments section.
Note
Some application programs make use of control key sequences. See the
Control key chart on page A-3 of this appendix.
For the following commands that use only 0 or 1 for the variable,
either the ASCII codes 0 and 1 or the ASCII characters 0 and 1 can be
used:
Esc s, Esc u, Esc x, Esc p, ESC w, ESC s, ESc -, ESC %,
ESC t, and ESC w
For example, in BASIC you can turn on double-width with either of
these statements:
LPRINT CHR$(27);"W";CHRS(l)-ASCII Code
LPRINT CHR$(27);'W";'l "-ASCII Character
correspond to:
These
ESC W SOH or EXW 1
Examples
The simplest type of command consists of sending a single character
to the printer. For instance, to print in condensed mode, you would
send the code 15. The code format is:
ASCII code: SI
Decimal: 15
Hexadecimal: OF
A - 2
