fgl_getkey()
Waits for a keystroke and returns the key number.
Syntax
fgl_getkey()
RETURNS INTEGERUsage
fgl_getkey() waits for a keystroke and returns the
key code
corresponding to the pressed physical key.
It is recommended to only use this function in text mode.
Unlike fgl_lastkey(), which can return a value indicating
the logical effect of whatever key the user pressed,fgl_getkey()
returns an integer representing the key code of the physical key that the user pressed.
The fgl_getkey() function recognizes the same codes for keys that the
fgl_keyval()
function returns. Unlike fgl_keyval(), which can only return keystrokes
that are entered during dialogs, fgl_getkey() can be called outside
a dialog context.
