As mav said, conversion now will eliminate some of the headaches later. I have used Sybase and MS SQL Server for some time and have found that they are very similar ... they were the same program until the late 80's, so it figures. If you cannot convert, i suggest the DBD::Sybase solution ... but even better would be trying to convert to sybase (free linux version (if i recall), and sp's like MSSQL).
always more than one way to skin an amoebae
