FUNCTION: Input Variable
DESCRIPTION:
The IN command allows a variable to be input from a keyboard. When the IN command is
executed in a program, the prompt message is displayed. The operator then enters the variable

name.
The IN command holds up execution of following commands in a program until a carriage return
or semicolon is detected. If no value is given prior to a semicolon or carriage return, the
previous variable value is kept. Input Interrupts, Error Interrupts and Limit Switch Interrupts
will still be active.
The IN command may only be used in thread 0.
