What is Clip ?

Just extracted this information from the Guestbook entry by Daniel Pascuel...

Fully compatible with CA-Clipper with some new possibilities.

slight incompability with CA-Clipper, which may be resolved easily, using the "search and replace" method. In addition it can compile to C program, byte-code, dynamic library and mixed C+byte-code.

Very fast and efficient OO-model.

Difference from CA-Clipper reveals itself in part of descriptions and making an object, but in part of using the ready objects syntax and logic of functioning is completely the same.
It is possible to write programs on CLIP, without using other syntax excepting OOP.
Initial support syntax from FS,CAVO,FoxPro.
C-API. has much more possibilities than CA-Clipper.

Full international support .
Including adjustment on any code page of any language on any keyboard (with stelnet emulator only or on consoles), substitution of string constants during execution and changing a logic of functioning with strings, given for functions alpha, digit, lower, upper, subscripted weight factors etc. Support two-bytes charsets BIG5, GB, may be Korean, Japan too.

GUI, based on GTK.
Provides using of all widgets and processing the events

Using of dynamic libraries, loading and execution of the byte-code from external files ( in run-time, too ).

up to Clipper 5.3 (support of objects menu, button, check and other get-objects), as well as standard classes tbrowse,get,error.

Are implemented a lot of CA_Tools functions, including all functions for processing the lines, dates, files, mathematicians.

support all SIX functions and features


VFP data types; datetime,currency

RDD allows to use your own drivers, as well as use a driver, combined from several different drivers.

RDD also allows to use only OO-style, without using of aliases

Multitask support.
Builtin simple non-preemptive multitask model

CODB - CLIP Object Data Base.
Library and utils for object storehouse

libraries and classes for direct access to SQL-servers (PG,MySql,Oracle,Interbase)
ODBC and ODBC bridge to Windows drivers.
SQL-interpreter and commands, compatible with FoxPro
Other possibilities .

Overloading operators for objects.

Support of regular expressions.

function for TCP/IP sockets connections

COM_() functions

Rushmore like technology, but more fast and efficient.

Support of very-large-scale numbers with unlimited accuracy.

Support of graphic files PNG,GD,JPEG and primitives like lines, rectangles, firing ranges, circumferences etc.

Several common classes for word processorses, html/cgi programms.

Several utilities for interpreting the patterns of the documents, www_sql,clip_bl, clip_blank, clip_sql, clip_hindex, clip_hseek etc.

multiwindows interactive debugger.

Supported OS’es.
Linux, FreeBSD, OpenBSD, SPARC & x86 Solaris, IBM mainframe with TurboLinux, Win32 ( with CYGWIN development tools)

  1. Hi CCH,

    Thank you for the information about Clip!!!

    I went to the site It has 2 types of license 1) GPL and 2) Commercial.

    I have some questions about clip:-

    1) Is there any IDE for Clip?
    2) It is compared with CA Clipper ver 5.3. Can we compare it with modern xbase compiler like Harbour / xHarbour and libraries like HMG, MiniGui Ext, hwgui?




Welcome to Clipper... Clipper... Clipper

In 1997, then using Delphi 3, I had already created 32-bits Windows applications for HRIS, ERP and CRM. In 2007, using Ruby on Rails, an AJAX powered CRM site running on Apache & MySQL was created and I am now using Visual Studio .Net 2008 to create web-based projects and Delphi 7 for Win32 applications using SQL2005 & DBFCDX.

So, why then am I reviving the Original Clipper... Clipper... Clipper via a Blog as CA-Clipper is a programming language for the DOS world ? Believe it or not, there are still some clients using my mission-critical CA-Clipper applications for DOS installed in the late 80's and up to the mid 90's. This is testimony to CA-Clipper's robustness as a language :-)

With the widespread introduction of Windows 7 64-bits as the standard O/S for new Windows based PCs & Notebooks, CA-Clipper EXE simply will not work and it has become imperative for Clipper programmers to migrate immediately to Harbour to build 32/64 bits EXEs

Since 28th January 2009, this blog has been read by 134,389 (10/3/11 - 39,277) unique visitors (of which 45,151 (10/3/11 - 13,929) are returning visitors) from 103 countries and 1,574 cities & towns in Europe (37; 764 cities), North America (3; 373 cities) , Central America & Caribeans (6; 13 cities), South America(10; 226 cities), Africa & Middle-East (12; 44 cities) , Asia-Pacific (21; 175 cities). So, obviously Clipper is Alive & Well : -)

TIA & Enjoy ! (10th October 2012, 11:05; 13th November 2015)

Original Welcome Page for Clipper... Clipper... Clipper

This is the original Welcome Page for Clipper... Clipper... Clipper, which I am republishing for historical and sentimental reasons. The only changes that I have made was to fix all the broken links. BTW, the counter from is still working :-)

Welcome to Chee Chong Hwa's Malaysian WWW web site which is dedicated to Clipperheads throughout the world.

This site started out as a teeny-weeny section of Who the heck is Chee Chong Hwa ? and has graduated into a full blown web site of more than 140 pages (actually hundreds of A4 size pages) ! This is due to its growing popularity and tremendous encouragements from visiting Clipperheads from 100 countries worldwide, from North America, Central America, Caribbean, South America, Europe, Middle-East, Africa and Asia-Pacific. Thanx Clipperheads, you all made this happen !

What is Clipper ?

You may ask, what is this Clipper stuff ? Could Clipper be something to do with sailing as it is the name of a very fast sailing American ship in the 19th century ?

Well, Clipper or to be precise, CA-Clipper is the premier PC-Software development tool for DOS. It was first developed by Nantucket Corporation initially as a compiler for dBase3+ programs. Since then, CA-Clipper has evolved away from its x-base roots with the introduction of lexical scoping & pre-defined objects like TBrowse. As at today, the most stable version ofClipper is 5.2e while the latest version, 5.3a was introduced on 21 May 1996.

As at 11th November, 1996, an unofficial 5.3a fixes file was made available by Jo French. See the About CA-Clipper 5.3a section for more details. BTW, Jo French uploaded the revised 5.3a fixes file on 20th November, 1996.

Latest News

The latest news is that CA has finally released the long-awaited 5.3b patch on 21 May, 1997.

For 5.3b users, you must a take a look at Jo French's comments on unfixed bugs in 5.3b.

BTW, have you used Click ? If you're a serious Clipperprogrammer and need an excellent code formatter, Click is a natural choice. How to get it ? Simple, access Phil Barnett's site via my Cool Clipper Sites.

32-bits Clipper for Windows ?

Have you tried Xbase ++ ? Well, I have and compared to Delphi (my current Windows programming tool of choice), I'm still sticking to Delphi.

Anyway, you should visit the Alaska Home Page. Give it a chance and then draw your own conclusions !.
