Informix 4GL and NT Server?

Hello, We are considering purchasing a piece of software that is written in Informix 4GL. The firm selling the software would like to also sell us a UNIX server to run it on. As we are running a network of NT Servers, I would like to avoid introducing a new type of OS into the network if at all possible. I tried searching through the Informix web site, but I could not find any information on whether or not Informix 4GL is supported on Windows NT. Could someone please let me know if this is possible or not? Also, do we, as the end users of this software, need to purchase Informix 4GL licenses in order to use this software? We have no intention of developing anything in Informix 4GL. I would greatly appreciate it if you could answer any of these questions. thank you, Deniz Akkus akkus@ibm.net PS. I will check the newsgroup, but would be delighted if you could send me email -- sometimes I get the newsfeed rather late it seems.
