You have to use integer types, not pointers (e.g. char *), structs,
classes, or floating point types in a switch. You need to use if
statements to get what you want:

if (strcmp(the_string, string1) == 0) {
  // String 1.
} else if (strcmp(the_string, string2) == 0) {
  // String 2.
} else if (..........
.....
} else {
  // Default case.
}

Of course with this you can't get the "fall-through" behavior, it's as
though every case is ended with a break, and the default case is
forced to be last. Any common behavior several cases must use can be
moved into a function that those cases call.

Incidentally, this question is about C/C++ programming in general and
not DJGPP-specific, and the language features involved are the same in
C and in C++, so this is a question better asked in comp.lang.c.
