The question is $ moot, however, with the advent of the LIM 4.0 standard which I believe they $ have all agreed (thankfully) to subscribe. AQA was an extension to LIM EMS 3.2 designed by AST, Quadram and Ashton- Tate. I'm not entirely sure of what differences it had; however, there were extra calls available (perhaps AQA is where the idea of more than 4 logical pages came from?). Fortunately, LIM included AQA in the EMS 4.0 specification, so programs written to require AQA will work under EMS 4.0. BTW, are there any programs out there (common ones, I mean) that require either AQA or EMS 4.0? -- Stephen M.
