My last message-------- I'm trying to open a resource file as raw data, then read/write to/from it. I'm doing this for downloading & uploading in my communications program. I found out, from the people @ pixmix, how to do the opening part. I now need to know how to read/write. Here is my routine for opening resource files.... To clarify--------- I need a futurebasic-compatible version of the toolbox calls "FSRead" and "FSWrite" (from Inside Macintosh). FutureBasic doesn't recognize these two calls. Thanks again.
