A character set is defined as 128 character positions. If more than 128 character positions are required, the set is divided in two and is designated left half (LH) for positions 1 through 127 and right half (RH) for positions 128 through 255. The MSB determines if the character set is placed in the left half (0 through 7F) or the right half (80 through FF) of the 8-bit character set table. An MSB of zero places the character set in the left half, MSB of one, in the right half.

Note: The hex value 1B (left half) is reserved for use as the ASCII escape control character (ESC). Any graphic defined at this location is not printed.

The error message FONT NOT AVAILABLE occurs if the value of n is not specified or is out of range.
