<B>INKEY$ Most Recent Character at Keyboard</B>
|
|
|
|
<U>s$</U> = <B>INKEY$</B>
|
|
|
|
Returns, without echo, the character most recently entered into the
|
|
keyboard buffer, or a null string if no character is pending.
|
|
|
|
----------------------------------------------------------------------
|
|
|
|
<B>Notes:</B> The system variable INKEY$ must be assigned to an ordinary
|
|
string variable before it can be used in a BASIC
|
|
statement.
|
|
|
|
If the most recent character is one of the 255 IBM ASCII
|
|
characters, INKEY$ returns that character only. If the
|
|
most recent character is a "special" character--a function
|
|
key or a cursor keypress, for example--INKEY$ returns a
|
|
two-byte string; the first byte is 00h, and the second
|
|
byte is the extended code corresponding to the key
|
|
pressed.
|
|
|
|
If a key defined with the KEY statement is pressed, then
|
|
INKEY$ will return with the sequence of characters mapped
|
|
to the key as if the characters had been entered
|
|
independently.
|
|
|
|
Cursor control keys, such as TAB and BACKSPACE, will be
|
|
returned to INKEY$ without processing (in "raw" mode).
|
|
|
|
The following keys have special functions and will not be
|
|
returned through INKEY$:
|
|
|
|
Ctrl-Break Terminates the program unless the
|
|
Keyboard break option in the
|
|
Options menu was turned off.
|
|
Ctrl-Alt-Del Resets the computer system.
|
|
Ctrl-NumLock Suspends the system.
|
|
Shift-PrtScrn Prints the current screen display.
