   The ^C is very easy to detect. You must look in tc_sigrecvd to find
a sigbreakf_ctrl_c. The following code does this

      move.l  4,a6   ; execbase
      move.l  thistask(a6),a0  ; my task structure
      move.l  tc_sigrecvd(a0),d0 ;signals we have received
      andi.l  #sigbeakf_ctrl_c,d0   ; the ^c flags
      bne     userdidhit^c  ; a one bit in tc_sigrecvd means we were signaled
      whatever you were doing.....


    if you want to actually wait for a ^c, do

      move.l  4,a6
      move.l  #sigbreakf_ctrl_c,d0
      jsr     _LVOWait(a6)
     etc,etc,etc....

(note that my upper case/lower case in the symbols is frequently not what
Commodore/Amiga intended. Mixed case in symbols is disgusting!)
