As you are probably aware, Clipper apps being 16-bits cannot run on 64-bits Windows 7. For it to do so, it must be converted to 32-bits by using the Harbour or xHarbour. I had previously show how to do so in3-part series.
EMN2016 wrote:I downloaded and installed HMG version 3.4.2 on my Windows 7 64 bits. I would like to make a few changes on an old Clipper software and recompile it. The extensions of the files are:.fmt,.scr and.prg. Is there a way I can import this files to HMG, or must I rewrite the whole software? Pure Clipper applications are character mode, whereas HMG has only a GUI front end. It is true that HMG includes Harbour, and that Harbour is a superclone of Clipper that may include character mode libraries, but HMG does not include these character mode libraries, so I don't see how HMG could compile a Clipper app. You may want to try MiniGui () instead, which is similar to HMG and does include character mode libraries and other support for building character mode apps.
Within MiniGui, look at BATCH Compile.bat, which has a /C flag for compiling in console mode (character mode). MiniGui is primarily intended for GUI apps and does not include any character mode samples. My program Data Globe () is a character mode app that has a batch file for compiling in MiniGui. Dragancesu is right that you may have a FoxPro app. In that case, Harbour probably won't work. But I think that is unlikely, since.fmt files were obsolete in FoxPro.
Other dBase clones may have allowed.fmt files too, such as DBXL and FoxBase. These also probably won't work with Harbour. There were some GUI libraries for Clipper, such as Clip4Win and FiveWin. These are not compatible with HMG and MiniGui, but they did not use.fmt files, so this is also unlikely. I also have old Clipper 5 programs, 24 rows, 80 columns as it was in DOS, nothing graphic.
I compiled them like this: 1) Modify in Windows the environment variable PATH. I use Windows 10 Home. Goto SYSTEM, click Advanced System Settings, click Environment Variables, click PATH in the System Variables, click Edit, insert at the bottom a new line C: HMG MINGW BIN (C: HMG is the folder where I installed HMG.3.4.2.Setup.exe) 2) Create a bat-file to compile your old DOS Clipper program. I included an example in attachment NT.ZIP. The BAT-file has only one line.
This article is written in in response to a comment left on Clipper. Clipper by Terry Carrol on 3rd July 2011 who asked I’d like to know if there is an easy migration from Clipper to something else that I could make my Clipper program work on a 64-bit machine.'
As you are probably aware, Clipper apps being 16-bits cannot run on 64-bits Windows 7. For it to do so, it must be converted to 32-bits by using the Harbour or xHarbour. I had previously show how to do so in3-part series. In 1997, then using 3, I had already created 32-bits Windows applications for HRIS, ERP and CRM. In 2007, using 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. Iptv hack. So, why then am I reviving the 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:-).
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 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?
