informix/sybase

My fingers don't even know what they are typing. I will try this one more time. I previously wrote concerning porting informix to Sequent when I really ment informix to cybase. Then in my infinate knowledge I tried again and gave the wrong address. My appoligies to WALT. So here goes again: We have a client that may decide to switch to cybase but still would like to use our applications. So: If anyone has any pointers or traps to look for or any information concerning doing this I would appreciate all comments. Also is there any tools available for doing this. Our application uses i4gl, r4gl,esqlc and other C functions. All help and hints appreciated. Thanks
