----------------------------------------------------------------------
In this file are summarized the additions and modifications made to
cbase this release. Users upgrading from a previous release should
read it carefully.
cbase 1.0.2 Release Notes
-------------------------
o
o Function prototype form used for function definitions if AC_PROTO
defined.
o Import functions modified to accept blank fields for numeric types.
Blank numeric fields are now interpreted as 0.
o consts removed from cbimp.
o cbexp fixed to not print extra trailing field delimiter.
o Bug importing escape sequence \nnn for t_char and t_uchar fixed.
o Bug detecting eof in cbimport fixed.
o Bug detecting corrupt database on open fixed.
o cbmkndx and cbrmndx functions added.
o nelems macro added.
o SINGLE_USER macro added.
o DOS file locking added.
o DOS library names changed to more customary form where memory model
is first character rather than last.
o Batch files for Borland C++ and Microsoft C added.
cbase 1.0.1 Release Notes
-------------------------
o AC_* macros (see blkio release notes) used in place of __STDC__ to
detect ANSI compatibility.
o t_cistring (case-insensitive string) data type added.

o cbimport has been modified to continue importing records following
the encounter of a record with an illegal duplicate key.
o cblock fixed to unlock data and key files in reverse order.
o Locking bug fixed in btree and blkio.
cbase 1.0 Release Notes
-----------------------
o The parameter list of the cbcreate and cbopen functions have been
modified. The original functions were
int cbcreate(char *cbname, size_t recsize,
cbfield_t fields[], size_t fldcnt);
int cbopen(char *cbname, char *type,
cbfield_t fields[], size_t fldcnt);
The new functions are
int cbcreate(char *cbname, size_t recsize,
int fldc, cbfield_t fldv[]);
int cbopen(char *cbname, char *type,
int fldc, cbfield_t fldv[]);
o The cbfield_t bit flags CBFKEY and CBFUNIQ have been changed to
CB_FKEY and CB_FUNIQ.
o All key cursors are positioned to null when a record is deleted.
o Field numbering now begins at zero.
o Because of an enhancement made to the btree library, it is no longer
necessary to include the record position in the data type comparison
functions when defining new data types.
o The functions cbimport and cbexport have been added to import and
export data to printable files. When adding a new data type,
an import function and an export function must be provided in
addition to the comparison function.
o There is no longer a maximum number of cbase fields. The fldv array
is now dynamically allocated when a cbase is opened.
o cbclose bug fixed. Would not close first key file.
o function prototypes used if __STDC__ == 1.
o const used if __STDC__ == 1.
Citadel 91/09/23
o long double data types (t_ldouble, t_ldoublev) enabled if __STDC__
== 1.
o cblock sets the cursors to null when unlocking.
o A pair of functions for converting names between the formats
last-name-first and first-name-first has been provided. fmltolfm
and lfmtofml are located in the file fml.c in the example program
directory.
o -A compiler option used in Turbo C installation batch file to set
__STDC__ to 1.
o In the blkio library, bpos_t has been changed from size_t to
unsigned long. See the blkio library release notes for explanation
of the effects of this change.

Very nice! Thank you for this wonderful archive. I wonder why I found it only now. Long live the BBS file archives!
This is so awesome! 😀 I’d be cool if you could download an entire archive of this at once, though.
But one thing that puzzles me is the “mtswslnkmcjklsdlsbdmMICROSOFT” string. There is an article about it here. It is definitely worth a read: http://www.os2museum.com/wp/mtswslnk/
