LINPUT

Function

LINPUT obtains a line of data from HUNTER's RS-232 port.

Syntax

LINPUT [;]["prompt string";] variable name

Examples

LINPUT A

Inputs from the serial port a numeric value and places it in variable A.

LINPUT "PARAMETER VALUES" A,B,C

Input the values of A, B and C with the prompt message:

PARAMETER VALUES
?

Remarks

Note that input lines are always terminated on reception of a carriage return (CR) character.

LINPUT cannot be used as a direct statement.

A prompt message can be displayed by the LINPUT statement. A string variable name or a literal string is required as an argument. Multiple variables can be strung together, separated by commas.

The characters input from the serial input port are NOT echoed to the screen.

A comma following the prompt message will suppress LINPUT's '?' prompt.

If LINPUT's argument is a simple variable and an invalid entry is made, LINPUT will simply re-prompt without an error message. An example is:

10 LINPUT A

HUNTER receives 'HELLO'. After 'CR', LINPUT generates a loud 'bleep' and re-prompts on the next line.

While the HUNTER is waiting for the first character to be received from the port, it will 'bleep' at 30 second intervals.
