where n1 + 256 n2 define the number of data bytes to follow.
DATA = ASCII characters for the dot pattern bytes.
NOTE: The DATA can be expressed in a CHR$(DATA) format with the appropriate
decimal values of the ASCII characters supplied especially in cases where the dot patĆ
terns of nonprintable characters are required.
Comment For detailed information, refer to the Bit Image section in the Graphics chapĆ
ter.
Example The following example produces a pattern of Single Density Bit Image graphĆ
ics. The 9 data bit pattern is repeated 27 times. Compare this example to the
double density and quadruple density examples.
NOTE: Depending on the host computer system, it may be necessary to include a width
statement within the BASIC program.
