Bullet Is...

 Bullet/X is a database engine toolkit for 32-bit enhanced DOS compilers and
 extenders.  It provides pre-built and tested access methods to data and
 index files for application programmers.  It is not an end-user Database
 Management System (DBMS), but it is a tool that could be used to develop
 one.  Bullet is compact, efficient, and  very fast.  It can be configured
 to use custom key-build, user sort-compare, and expression-parser routines
 to extend the built-in functionality.  All OS API calls made by Bullet can
 be replaced with custom calls, using most any compiler language.

 The standard data format is DBF (dBASE 3+ and later).  The supported memo
 format is DBT (dBASE 5 and later).  Index-only support can be enabled and
 with this any data file format may be used (the data maintained by the
 programmer then).  Also, the DBF standard may be extended by using binary
 field values and fields larger than 254 bytes.  Index files are
 NLS-compatible and use an efficient b-tree structure.  Files may be any size
 supported by the OS, up to 4GB.  Up to 1024 files may be opened and in use
 by any one process, with any number of processes active.

 The Bullet API consists of a wide assortment of routines, from low-level OS
 calls to high-level transaction-list routines that can process hundreds of
 files per transaction, with roll-back on error.  Network/multi-user
 support is included, and makes use of operating system features such as
 atomic re-locking (if available), and shared locks that allow other
 processes read-access to locked files.

 Also available are Bullet/95, for Win32 32-bit compilers (Win95, NT, Win32s);
 Bullet/2 for OS/2, and Bullet/2 REXX.  Bullet for 16-bit compilers is also
 available.
