Programming Examples
Examples in this manual have been formatted to be processed by a simple
BASIC program. The BASIC program reads an input file and writes data to an
output file. Printer commands may be entered into the input file in a
hexadecimal format and enclosed with opening and closing delimiters.
BASIC program. The BASIC program reads an input file and writes data to an
output file. Printer commands may be entered into the input file in a
hexadecimal format and enclosed with opening and closing delimiters.
The opening delimiter is a less-than symbol, ’<’, followed by an ’x’. The ’x’ may
be either upper or lower case. The closing delimiter is a greater-than symbol,
’>’.
be either upper or lower case. The closing delimiter is a greater-than symbol,
’>’.
Within the delimiters, hexadecimal data must be presented in two-digit pairs.
White space, blanks, carriage returns and line feeds may be used between the
pairs. In addition, a comment may be added to the end of a line by using a
minus sign, ’-’, at the start of the comment. All data after a minus sign is ignored
until a carriage return or line feed is encountered.

All of the examples use this encoding method and have been tested using the
following BASIC program:
