Type Program control command
Syntax ON expression GOTO label [,label[,...]]
Description The expression is evaluated and then the integer part is used to select a
label from the list. If the expression has the value 1 then the first label is
used, 2 then the second label is used, and so on. If the value of the
expression is less than 1 or greater than the number of labels then an
error occurs. Once the label is selected, subroutine
GOTO jump to that
label is performed.
Arguments • expression
Any valid BASIC expression.
• label
Any valid label in the program.
Example REPEAT
GET #5,char
UNTIL 1<=char and char<=3
ON char GOTO mover,stopper,change

Type I/O command
Syntax OP(output_number, value)
OP(binary_pattern)
OP
Description The OP command sets one or more outputs or returns the state of the
first 24 outputs. OP has three different forms depending on the number
of arguments.
•
Command OP(output_number,value) sets a single output channel.
The range of output_number depends on the number of additional
digital I/O connected to the PLC and value is the value to be output,
either 0 or 1.
• Command OP(binary_pattern) sets the binary pattern to the 24 out-
puts according to the value set by binary_pattern .
• Function OP (without arguments) returns the status of the first 24
outputs. This allows multiple outputs to be set without corrupting oth-
ers which are not to be changed.
Note: The first 8 outputs (0 to 7) do not physically exist on the CJ1W-
MCH72. They can not be written to and will always return 0.
Arguments • output_number
The number of the output to be set. The range for this parameter
depends on the number of additional digital I/O connected to the
PLC. If there are no digital I/O connected, the range for this parame-
ter is 8..31
• value
The value to be output, either OFF (0) or ON (1). All non-0 values
are considered as ON.
• binary_pattern
The integer equivalent of the binary pattern is to be output.
