 In Turbo Pascal, use KeyPressed. Both Microsoft C and Turbo C offer the
 kbhit() function. All of these tell you whether a key has been pressed.
 If no key has been pressed, they return that information to your
 program. If a keystroke is waiting, they tell your program that but
 leave the key in the input buffer.

 You can use the BIOS call, INT 16 AH=01 or 11, to check whether an
 actual keystroke is waiting; or the DOS call, INT 21 AH=0B, to check for
 a keystroke from stdin (subject to redirection). See Ralf Brown's
 interrupt list <Q:02.03> [What and where is Ralf Brown's interrupt
 list?].

The Borland/Turbo "floating point formats not linked" error may also be caused

by specifying the libraries in the wrong order in the TLINK command.  Try putting

the FP87 library first, then the MATHx library, then the Cx library (where x is

the memory model designator).  This, combined with the dummy FP function trick,

should solve the problem.
