I am developing a system for some people who use the Tetraplan accounting suite, version B.4. This has lots of stuff in it and was written using the C-ISAM library developed by Informix. All of this is running under SCO 386 Xenix on an Apricot machine. I have written an additional program which allows them to enter data in a format that they (for historical reasons) prefer. My program uses C-ISAM 3.10 to access the data files. The program works fine on its own, but whenever another user uses Tetraplan and opens (even just to read) a file that my system needs, I get locked out. I am using record level locking whenever I can - it just seems that Tetraplan is locking everything (except other Tetraplan users) out. After much messing around and failing to get straight answers from suppliers and distributors, I discover that Tetraplan is written with C-ISAM version 2.04. I have two questions - are the function calls in 2.04 identical to 3.10 will relinking with 2.04 solve my locking problem? All help appreciated. ========================================================================== Bill Thompson | +44 223 314176 (home) Acorn Computers | Geonet: GEO2:B.Thompson Cambridge | England | ========================================================================== "Evolution: entirely unpredictable, but trivially explicable"
