Are you talking about C?

int this_is_global=0;

void foo(void)
{
    this_is_global=7;
}

int main()
{
      printf("before: %d ", this_is_global);
      foo();
      printf(" after: %d\n", this_is_global);
}

Is it shell script? - the syntax depends on what shell you are using

echo $SHELL

will show you your shell. We need to know which shell you are using.

or better yet - to get the 'active' shell interpreter:

echo $0
