Here are a few rules to follow.

1) After FN pGreplaceRes, your resource handle is no longer valid. You must
use GETRESOURCE to re-get the handle

2) Never dispose of a resource handle. (i.e. don't use DISPOSEH,
DISPOSEHANDLE, KILLPICTURE, DISPOSEMENU, etc.)

3) Except in some very rare cases, you don't need to call RELEASERESOURCE.

4) If you detach a resource it is no longer a resource, but you still have
a handle in memory to contend with.

5) If you have to lock a resource handle or make it unpurgeable, use these
steps:

     hState = FN HGETSTATE(resHndl&)
     OSErr = FN HLOCK(resHndl&)

       REM do your stuff here...

     OSErr = FN HSETSTATE(resHndl&,hState)
