Your problem is that when you declared path as
    char *path;      /* A pointer */
you must pass path to pad_$create_window() as in
    pad_$create_window(*path, (short)strlen(path), ...);
ie you must derefernce path.  The reason is the differences in the ways
C and Pascal passes arguments.

Another way to fix the problem is
    char path[BUFSIZ];      /* An array */
    strcpy(path, "/sys/help/help.hlp");
    pad_$create_window(path, (short)strlen(path), ...);

You have to use either method whenever you uses any Aegis
subroutines that requires string arguments.
