OK. I understand what it is you're doing. Honestly, I do not know if XBasic could be used to do such a thing. But, the folks in the support forum are very knowledgeable and helpful. I will ask.

As for the laser emission lines, all I did was make a program to graphically display information from a database. I did not derive any of the data myself. Some time back I had made a graphic chart showing a few dozen visible laser lines and I wanted to improve upon that, but the chart would have ended up being several thousand pixels in dimension. Kind of hard to view on a monitor. So, I made a program that allowed one to search and display only those lines of interest.
