When something expects a "int *", you're not supposed to declare an "int *". That creates an empty pointer, pointing to nowhere, which will probably cause your program to crash when used!

What they want when they demand an "int *" is pointer to an integer, the address of an integer, so they can modify that integer.

Code:
int stat;

wait(&stat);

TITLE
Language::INTERCAL::Bytecode - intermediate language DESCRIPTION
The CLC-INTERCAL compiler works by producing bytecode from the program source; this bytecode can be interpreted to execute the program immediately; alternatively, a backend can produce something else from the bytecode, for example C or Perl source code which can then be compiled to your computer's native object format. The compiler itself is just some more bytecode. Thus, to produce the compiler you need a compiler compiler, and to produce that you need a compiler compiler compiler; to produce the latter you would need a compiler compiler compiler compiler, and so on to infinity. To simplify the programmer's life (eh?), the compiler compiler is able to compile itself, and is therefore identical to the compiler compiler compiler (etcetera). The programmer can start the process because a pre-compiled compiler compiler, in the form of bytecode, is provided with the CLC-INTERCAL distribution; this compiler compiler then is able to compile all other compilers, as well as to rebuild itself if need be. See the online manual or the HTML documentation included with the distribution for more information about this. SEE ALSO
