======

Function
--------

**LINCHR** inputs a single character from the RS-232 port.

Syntax
------

| LINCHR variable name
| LINCHR ["PROMPT STRING";] VARIABLE NAME

Examples
--------

::

   10 LINCHR "DECIMAL VALUE",A
   20 PRINT A
   30 GOTO 10

displays:

   DECIMAL VALUE 65
   DECIMAL VALUE 66

etc.

Remarks
-------

LINCHR does not wait for carriage return to be received and the
character input is not echoed to the screen. A prompt message is
displayed on the LCD screen as with :doc:`input`. Only one
variable will be received. The variable is set to the decimal value of
the character, as detailed in :doc:`../appendix/ascii-character-set`.

A comma following the prompt message will suppress the prompt character
'?'.

Characters input from the serial port are not echoed onto the screen.
