Here's what I have so far:

[16 Dec 92]

CA-Clipper 5.2 -- Why upgrade from CA-Clipper 5.01:

New Documentation --

     All documentation will be reprinted.  Functions previously
     included only in the Norton Guides online documentation will be
     included in the printed manuals.  New tutorials for novice
     programmers and basic network programming, and additional code
     samples, will be included.

API (Application Programming Interface) --

     Several APIs will be documented:

     VMM (Virtual Memory Manager) API:  Enables software developers
     to better utilize CA-Clipper's advanced features.  Programs
     written in C, Pascal and Assembly can use the VMM system to
     manage memory in a way consistent with CA-Clipper.

     RDD (Replaceable Database Drivers) API:  Developers will be able
     to create their own RDDs and thus have access to virtually any
     file format.

     GT (General Terminal) API:  Developers can create alternate
     screen drivers for CA-Clipper.  This enables, for instance,
     access to the graphic screen.

Additional RDDs --

     CA-Clipper 5.2 will contain several RDDs:

     The DBFNDX driver enables programmers to read and write dBASE
     III PLUS index files.

     The DBFNTXC driver was enhanced to allow conditional index
     creation and manipulation.  It also has a new faster locking
     mechanism which will improve performance in most network
     environments and a hook for the inclusion of a progress gauge
     during indexing.

     The DBFCDX driver enables programmers to create and manipulate
     FoxPro index files.

     The DBFPDX driver enables programmers to work with Paradox files.

     The DBFMDX driver enables programmers to create and maintain
     dBASE IV-compatible multi-tag index files.

All anomaly repair patches --

     CA-Clipper 5.2 will include all fixes which have been made
     available since the original version of CA-Clipper 5.01.  This
     will result in a more stable application development system.

Miscellaneous --

     CA-Clipper 5.2 will also have the following features:

     RSIS (Relocatable Screen Interface Specification) compliant
     screen I/O.  This enables faster screen writes under products
     like QEMM which relocate the screen buffer.

     LIM 4.0-compliant expanded memory management. The 8Mb memory
     barrier is removed under LIM 4.0 allowing access of up to 64Mb.
     It also gives better compatibility with TSRs and faster memory
     access.

     Enhanced debugger.


Hope that helps.
