SECTION 5. 13
LINPUT
5,13.6 Function LINPUT obtains a line of data from HUNTER's RS-232 port.
Syntax LINPUT [;] [ "prompt string"; l 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, Band C with the prompt message:
PARAMETER VALUES
?
Remarks Note that input lines are always terminated on reception of
a carriage return (CR) character.
VER.V09F
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.
NOTE: 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.
NOTE: While the HUNTER is waiting for the first character
to be received from the port, it will 'bleep' at 30 second
intervals.
