Description
The Loop start command marks the memory location where the portion of a repeatedly executed
command sequence begins.
This command is normally used together with the Loop repetition number command.
The Loop start command is of the delayed execution type and it occupies 2 memory locations.
The Loop repetition number command allows an instruction, a sequence or a whole program to
be repeated for the specified number of times.
The command must be followed by an argument ranging from 1 to 255, that specifies how many
times the portion of the program contained between the Loop start command and the Loop
repetition number has to be executed.
The sequence:
L0↓
•
•
•
L10↓
forces the command sequence included between L0 and L10 to be repeated ten times.
This command in normally used togheter with the Loop start command. If the loop starting point is
not specified, the interpreter repeats the sequence starting from the beginning of the program.
The Loop repetition number command is of the delayed execution type and it occupies 2 memory
locations.
The Memory save command allows the program currently stored in the RAM memory to be
permanently saved in the EEPROM.
The program can then be reloaded both automatically or under command. In the first case, it is
executed automatically at power on, while in the latter the X command must be issued.
The Memory save command is of the immediate execution type.
The Program enter command sets the GS-C200 in the programming mode and it allows a new
program to be entered in the memory.
The instruction doesn’t require any argument and it causes the cancellation of the program
contained in the RAM memory
The programming session is terminated by the Execute command. The Program enter command
is of the immediate execution type.
The Program enter command sets the GS-C200S in the programming mode and it allows a new
program to be entered in the memory. The instruction doesn’t require any argument and it causes
the cancellation of the program contained in the RAM memory.
The programming session is terminated either by the program exit or the Execute command.
The Program enter command is of the immediate execution type.
The Program exit command sets the GS-C200S in the execution mode and it allows the unit to
wait for a command. The instruction doesn’t require any argument. The Program exit command is
of the immediate execution type.
The Query command instructs the GS-C to send to the Host computer the program currently stored
in the RAM memory.
Every program instruction is separated by a carriage return (ASCII 13), and the program end is
evidenced by the transmission of a message ”END” that is the sequence terminator and it must be
recognized by the Host. The instruction does not require any argument. The Query command is of
the immediate execution type.
