**  Global Declarations
**
**	Virtually all non-local variable declarations are made in this
**	file.  Exceptions are those things which are initialized, which
**	are defined in "externs.c", and things which are local to one
**	program file.
**
**	So far as I know, nothing in here must be preinitialized to
**	zero.
**
**	You may have problems from the loader if you move this to a
**	different machine.  These things actually get allocated in each
**	source file, which UNIX allows; however, you may (on other
**	systems) have to change everything in here to be "extern" and
**	actually allocate stuff in "externs.c"
