If only we could remember them! :-) Ancient history remembered through the haze... In the beginning was C-ISAM, and then the original Informix product, which reached version 3.30 on Unix, and apparently 3.60 on DOS. This product did not use SQL. Then Informix-SQL 1.10 was released, with no support for NULLs; this was released in 1985 or early 1986, I believe. Then Informix-SQL 2.00 and Informix-4GL 1.00 were released in mid-1986; C-ISAM and ESQL/C had release numbers 3.00, I believe. This was also the point at which I started working with Informix products. My first task was to learn enough to be able to teach I4GL and ISQL 2.00, only to find that the machine I was to use for the course had ISQL 1.10 on it (it was a Z8000 box, and the superuser was called zeus, not root). Then Informix-SQL 2.10 and Informix-4GL 1.10 were released, and I think this was when I4GL-RDS and I4GL-ID appeared. Since Informix 3.30 was still relatively recent, the next versions were called ISQL 2.10.03 and I4GL et al 1.10.03 on Unix to avoid the ineveitable confusion if it was called Informix SQL 3.00; I believe the versions were 2.10.06 and 1.10.06 on DOS. Also, Informix-Turbo 1.10.03 was released, and it was pointed out as a future direction that SE would be separated from the ISQL and I4GL tools -- until then, the engine had always been distributed with ISQL, I4GL and I4GL-RDS (but not ID since you needed RDS to make any use of ID). To avoid confusion with Informix 3.30, the subsequent release was version 4.00 of Informix-SE, Informix-OnLine, ISQL and I4GL (and C-ISAM and ESQL/C) - there was never a 3.x version of the main products other than (perhaps) C-ISAM and ESQL/C. It was also at about this point that the Tools and Servers groups were split apart. Now, Plexus certainly had a hand in the Turbo to OnLine transition, but I don't know what versions they used -- they may even have had a 3.1 Turbo product, as the original questioner mentioned it. I don't know, and I don't think the original questioner has chimed in again to help clarify what they've got. It is safe to assume that any Turbo product is seriously out of date -- OnLine 5.00 was released effectively in January 1991 (officially 30th December 1990 or thereabouts), and there was a version 4.10 between 4.00 and 5.00. As to the connection question -- the revised opinion is that you should be able to use a network connection to an I-Net that matches the version of Turbo. I'm not wholly sure when I-Net arrived on the scene; I-Star definitely arrived with 4.00 and OnLine, but I-Net probably pre-dates that. However, it is not going to be officially supported, and an upgrade would be recommended. -- Jonathan Leffler (jleffler@informix.com, jleffler@earthlink.net) Guardian of DBD::Informix v0.62 -- see http://www.perl.com/CPAN #include <disclaimer.h>
