You are right, it's limted to 36 now, mybe not the best solution, and hardcoded...

Using the -F switch to load the data vectors from a different file, but using a standard layout is a pretty nice possibility if you always have the same data. If it's not clear to you what this feature is, I can give more explanations.
> Syam, could you possibly post two sample fiels (one binary, one ASCII) and more details on your workflow? Things like knowing whether you always look at the same vectors or not, or how many clicks are acceptable when loading new data, whether you always want to look at all vectors and how many there are in your files are all important information. Also, batch use cases would be interesting to mention, if you have some.
