KEYCODE

MarshallSoft GPS Component (MGC) application programs requires that you pass
a "key code" (32-bit integer) to mgcAttach. Use 0 for the shareware version.
For the registered version, you will be issued a 9 or 10 digit keycode that
matches your registered DLL, placed in KEYCODE.H in the APPS directory.

Error code -74 (MGC_BAD_KEY_CODE) is returned if the wrong key code is
passed.
