Hallo Mr. Claudio Fernandez Loquenz,

congratulations for your SDG-program, which achieved the 3rd place in the ABBUC software contest of 2008. I was very impressed about the great number of functions implemented in this package. I used statistics software like Statview and SPSS but could never believe something like this could be done on an ATARI 8. So my question is, if you have written (and used) this package for real work at the university or for medical research and is it still in use? Would be very interesting to know if the ATARI 8 is still "at work" somewhere.

Greetings and thanks for this software!

Michael

Hello Michael:

Thank you very much for your feedback. SDG was born precisely as an attempt to use in a single package several functions of descriptive statistics and inferential. In the 80s and 90s I used some software of statistical of ATARI such as SynStat and B/Graph, which were excellent. However, I decided to try to make use of software of statistical easier and more useful, by integrating various processes, some of them unpublished in ATARI, such as automatic creation of frequency tables and ANOVA for Design of
Experiments.

As a fan of ATARI, I have used SDG in the University for that job, especially in the field of design of experiments for agricultural research. Of course I also I use computers latest generation to processes data from large experiments.

SDG meant for me a personal challenge and now I'm creating version 2.0 that will use three system disks of to prevent the frequent exchange of disks to process data.

Best regards,

Claudio

Hello Claudio,

that is interesting. I also worked in a similar field. Please check your PN.

Greetings,

Michael

Hello Claudio,

I guess you spend "some" (nightly) hours on it and it's nice to hear that you are working on version 2.0. The SDG is written in Turbo Basic, right? Did you use a real ATARI or the emulator? At the moment I'm (re-)discovering my old Kyan Pascal System on the ATARI800Win-Emulator. In combination with the recently published XDOS 2.4 (winner of the contest), large disk images and high speed on the PC it is a very powerful tool. If you should consider using Pascal for ver 2.0, let me know. I could help you out with an ATR-Image. I could imagine, that pascal would make some things easier than Turbo Basic, especially with math/stats. On the other hand "never change..." !

Best regards,

Michael

Hmmmm, please don't use any more than 3, my SIO2USB just supports 3 disks

Hi

Indeed, SDG was programed with Turbo Basic. Knew of "Kyan Pascal" many years ago and is also a excellent language, but I'm more familiar with Basic.

Very good your idea to use XDOS 2.4, try it.

The initial structure of SDG was programed in a real "ATARI 800 xl", but subsequently became atr images discs in order to continue programming virtually in a emulator Atari800win, obviously was easier this way ...

But like I demanded many hours, days and even months of planning and work.

But since nothing is perfect, version 2.0 of SDG will have three disks system ... but, depending of module, will be used one at a time,so it can be made processes use only two drives: one for any of the system discs and other for data.

Best regards,

Claudio

Hello Claudio,

Your SDG is very impressive and I will try out some things with it.
Haven't seen something like that since BGraph and SynStat.


Since I prefer real ATARI 8 bit hardware I like to know if it is possible to run it from a hard drive or a high capacity floppy disc by copying everything to one drive.

And another question: is SDG written to be compiled so it can be run faster?

... if it is possible to run it from a hard drive or a high capacity floppy disc by copying everything to one drive.

That would be very helpful...

Hello Walter & Michael:

Thanks for your feedback. Of course it would be possible to install it on a higher-capacity disk (less than 360 Kb), as it is SDG with programs designed modules BASIC for each independent process. It would be enough copy all the modules BASIC to a single disc that a DOS Support increased capacity. I did the test and it works perfect using SpartaDOS32f (Download here SDG-ONE-System-Drive.atr image).
Perhaps I should make small changes in programs for avoid the call to insert a disk, or to avoid Option 1 Menu Initial as it now would be meaningless.

Speed is always sometahing that there should be, especially in the Construction of graphics, so the compilation of SDG is something that I have yet to perform.

Best Regards.
