** 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"
