nSeconds

Specifies the number of seconds to wait for a keystroke. If you do not specify a value for nSeconds, INKEY(В ) returns a value for a keystroke immediately. If nSeconds is 0, INKEY(В ) waits indefinitely for a keystroke.

cHideCursor

Shows or hides the cursor, or checks for a mouse click. The following table lists values for cHideCursor.

cHideCursor	Description
S	Show cursor.
H	Hide cursor.
M	Check for a mouse click.
E	Expand the keyboard macro if a keyboard macro is assigned to a key or key combination. To return successive values for each keystroke in a macro, execute INKEY(В ) repeatedly with E included.

Note:
If both S and H are included in cHideCursor, the latter character specified takes precedence. You can combine values for cHideCursor, for example, to check for a mouse click and show the cursor, include M and S. To check for a mouse click and hide the cursor, include H and M. INKEY(В ) disregards characters other than S, H, M, and E in cHideCursor.

Numeric. INKEY(В ) returns 0 if a key has not been pressed. If several keys are present in the type-ahead buffer, INKEY(В ) returns the value of the first key entered in the buffer. INKEY(В ) also returns the following values according to certain conditions:

• If M is included for cHideCursor, INKEY(В ) returns the value 151.
  
  
• If E is included, INKEY(В ) returns a value corresponding to the first keystroke assigned to the keyboard macro. If you omit E, INKEY(В ) returns the value for the key or key combination that triggers the keyboard macro.
  
  
• For single keys and key combinations using the SHIFT, CTRL, and ALT keys, the following table lists the return values for INKEY(В ). A dash (–) indicates that the key combination returns no value.
