Re: [Freedos-user] Redoing Clipper DB compiled app
I'm not sure about the AUTOEXEC.BAT lines, a space character is needed SET CLIPPER=F150; ...I also remember putting a semi-colon between each CLIPPER parameter a semi-colon at the end. My memory could be off or Harbor may not need that.

[Freedos-user] Redoing Clipper DB compiled app
I'm looking for remarks about porting and running a Clipper compiled dBase(.dbf files) application on FreeDOS. I've used some index add-on libraries which may be an issue in FreeDOS. I have little source code for the libraries. They and Clipper were created using Microsoft C 5.1 of long ago. I do still have a complete compiler distribution, updates may pose a challenge. I do have, believe it or not a working OS/2 Warp development system. I ran five virtual DOS sessions which were/are original IBM PC DOS 7 images. While way ahead of its time I'm concerned it has to fail at some point. This OS/2 might run on the first Pentium but that attempt may not be worth the effort. I could move to LINUX and oh-n mr. bill, Windows. I have some options. I'll just give FreeDOS a try with QEMU on LINUX and VMPlayer/VirtualBox on Windows. I could also do time consuming and extensive redevelopment using harbour-project.souceforge or xharbour.orgClipper clones. Time is money and redevelopment may have a long term return but if I can target FreeDOS cash flows immediately. Does anyone have any experience or suggestions about using existing Clipper applications on FreeDOS.

Jean, Thank you for your quick response. I to have worked with FoxPro for DOS and still have more that one license. I'll pull that package out to see what I might do with it.

Re: [Freedos-user] Redoing Clipper DB compiled app
Hi John, if you have Clipper-compiled sources, you can indeed try to compile them again with the free Harbour clone, as you already mentioned. There is also a wikipedia article for those who are new to the topic. As far as I remember, FreeDOS 1.0 came with a version of this, but it was quite big and needed OpenWatcom installed. On the other hand, porting command line Linux apps with DJGPP works reasonably well, as does running (sometimes no porting needed) of Matlab code in the free Octave system, so maybe Harbour just works? :-) https://en.wikipedia.org/wiki/Harbour_%28software%29 http://www.freedos.org/software/?prog=xharbour By the way, nice that you have OS/2 Warp around :-) I'm looking for remarks about porting and running a Clipper compiled dBase(.dbf files) application on FreeDOS.

Eric, I'll review the threads to see what might work. I guess based on you comments I should try FreeDOS and see what happens.
