PurgeSpace returns (in total) the total amount of space in bytes that
could be obtained by a general purge without actually doing
the purge; this amount includes space that is already free.
The maximum contiguous space in bytes, including already free space,
that could be obtained by a purge is returned in contig.
In Pascal:
Procedure PurgeSpace (VAR total,contig: LONGINT);
In C:
void pascal PurgeSpace(long *total, long *contig);
In Asm:
    Trap macro  _PurgeSpace
                _PurgeSpace ,SYS    (applies to system heap)
    On exit     A0:  contig (long word)
                D0:  total (long word)
