   I assume your refering to a programme that was compiled under MSC 4.0,
not while MSC is compiling.
   There are a couple of ways to handle a ^C.
   MSC provides the best way.  Look up signal() (page 350 Run Time
Library Manual).  Signal() will let you define what should go on when
a ^C is received by the programme.  In this way you can define how the 
programme should go through an orderly exit of the routine or the programme
itself.  The example on page 352 is a good example of this.
   You can also put the Console into the 'RAW' mode where MS-DOS does not
do any ^C checking.  This can be done with the dos call 'I/O Control for 
Devices', (44h).  And can be accessed through the intdos() function 
provided by MSC 4.0.
