"\x0D\x1A".
- Added SetEofChar()

then 255 characters. Determined by a char field and a
decimal field > 0.

- Fix for incrementing CurRec on an AppendRecord().
- Fix in dump record to handle large fields
exp.cpp and expfunc.cpp
- Added DESCEND(). Only works for dates.
- Added DTOS(). Date to string.
- Added RECNO() returns the current record number.
- Added 2 and 3 parameter versions of STR()
- Added STRZERO()
- Small expression parsing fix
expproc.cpp

ndx.cpp
- Changed NodeLink to NdxNodeLink
- Moved common instance variables to index.cpp
xbase.cpp
- Added GetULong(), PutUShort(), PutULong(). Not sure if
they're necessary.
New Files
index.cpp Index Base class for ndx and ntx classes
index.h
ntx.cpp Clipper NTX class.
ntx.h
To Do:
- Some methods are almost identical in ntx.cpp and
ndx.cpp. These could be moved to index.cpp.

* xbase/lock.cpp (LockIndex): unrenamed symbol
Some HAVE_EXCEPTIONS cleanup:
* xbase/dbf.cpp (CreateDatabase, OpenDatabase, AddNdxToIxList):
xb_memory_error applied
(GetNextRecord, GetPrevRecord): xb_eof_error applied
* xbase/expproc.cpp (ProcessOperator): xb_memory_error applied
* xbase/memo.cpp (CreateMemoFile): xb_memory_error applied
* xbase/ndx.cpp (UncloneNodeChain, CreateIndex, AddKey):
xb_memory_error applied
(GetNextKey, GetPrevKey): xb_eof_error applied
* xbase/xbase.cpp: xbexcept.h included unconditionally
(AddDbfToDbfList): xb_memory_error applied
* xbase/xbexcept.h: xbStrError() prototype
* xbase/xbexcept.cpp (xbStrError): moved outside HAVE_EXCEPTIONS.
It is useful anyway.
egcs warnings fixes:
* xbase/xbase.h (xbXBase::xbXBase): Redundant scope qualifier removed
* xbase/xstack.h (xbStack::xbStack): Redundant scope qualifier removed
* xbase/exp.h(class xbExpn): Token( void ) removed. Not seen
anywhere else.
