* SET-BLOCKFILE ( fid -- ) win32for

win32forth uses a system-filedescriptor where -1 means unused
in the BLOCKHANDLE, but we use a "FILE*"-like structure, so NULL
means NOT-IN-USE. Here we set it.

* USING ( 'filename' -- ) obsolete

use filename as a block file
OBSOLETE!! use OPEN-BLOCKFILE

EXTENSIONS block_misc ordinary primitive

* USING-NEW ( 'filename' -- ) obsolete

like USING but can create the file
OBSOLETE!! use CREATE-BLOCKFILE
