COMMAND FORMAT
The general format of a command is a two character mnemonic (AA).
Both upper and lower case are accepted. Depending on the command,
it could also have optional or required preceding (xx) and/or following
(nn) parameters.
BLANK SPACES
Blank spaces are allowed and ignored between parameters and
commands. For the clarity of the program and memory saving
considerations, use blank spaces with restraint. The following two
commands are equivalent.
2 PA 1000
2PA1000
but the first example is very confusing and uses more than twice the
memory.
COMMAND LINE
Commands are executed line by line. A line can consist of one or a
number of commands. The controller will interpret the commands in
the order they are received and execute them sequentially. This means
that commands issued on the same line are executed significantly
closer to each other than if they would be issued on separate lines. The
maximum number of characters allowed on a command line is 80.
SEPARATOR
Commands issued on the same line must be separated by semicolons ( ; ).
Multiple parameters issued for the same command are separated by
commas (,).
TERMINATOR
Each command line must end with a line terminator, i.e., carriage
return.
