  12. Hi,
  13.  
  14. Karim asks how to get a preprocessor macro recognised inside
  15. a string.  The answer, at least in ANSI C, is to use the
  16. stringising operator and string concatenation:
  17.  
  18. #define JUNK 50
  19. static char *junk = #JUNK " ways to leave your lover"
  20.  
  21. The construct #JUNK generates the string "50", which is
  22. concatenated with its neighbour.
  23.  
  24. Regards,
  25.
