For those programmers wishing to write and use programs longer than
16 steps, it is possible to take advantage of contiguous program
memory within the PNG. As there is space for ten programs of 16
steps each, a program starting at PRG#0 STP#00 could take advantage
of the complete 160 step program space. In the absence of an 'EXIT'
command instruction, the program will continue from PRG#0 STP#15 to
PRG#1 STP#00. By similar planning, a program starting at PRG#1 could
contain up to 16 X 9 = 144 program steps. Of course, writing
programs longer than 16 steps makes the used program space unusable
for programs that would normally fit into the over-flow space. Bear
in mind, too, that the GOTO command can only branch within the true
space of the current program, and that the programming 'language'
does not yet support conditional branch instructions.
EXECUTING A STORED PROGRAM SEQUENCE
To execute a previously stored program sequence, press the 'EXEC'
key on the PNG's Keypad. The following Information Display will
appear:
Enter the number of the program to be executed, followed by the
'ENTER' key. The selected program will be executed, beginning with
the first frame of the sequence. As the steps of the program are
executed, Information Displays of the following format will appear:
