No, no, no.  Write that in Haskell instead, like this:


#Switch<C++RTTI>(ON)
#include <stdio.h> AND <stdlib.h>
#use FORTRAN_RUNTIME_MODULE but compile_as(Cobol)
#Incorporate{PascalInterpreter}  but run_as(Haskell)
use strict;
use warnings;
sub RecursiveFact
{
my $n=shift;
if ($n > 1)
{
return $n * RecursiveFact($n-1);
}
else
{
return 1;
}
}
printf("%d\n",RecursiveFact($ARGV[0]));


Yep, that there Haskell program should solve these C++
problems you've been having with that Oberon program of yours,
by injecting a bit of Perlescence.


Or just write it in Fortran and be done with it:


/* This is a really lovely Fortran program. */
#include <stdio.h>
#include <stdlib.h>
int RecursiveFact (int n)
{
return n>1?n*RecursiveFact(n-1):1;
}
int main (int argc, char ** argv)
{
printf("%d", RecursiveFact(atoi(argv[1])));
return 0;
}
