Pick/Basic Programming Language

I am not so sure if you mean something on Basic/QBasic. If that is it, Visit this site for a lot of sites offering free online tutorial on this language.

Hope this helps!

Goto this site http://www.rainingdata.com , then click on services and support. This should be what you need. There is a PDF version of Jonathon Sisk's book, plus some other technical data. It is so difficult to find books on PICK anymore. Good Luck!

I don't know how basic you need the information to be presented, because it's going to be difficult anyway to learn the PICK environment. Some of the interesting aspects of the PICK system are how it looks at dates as a number of days since it's inception and how it converts that number into an actual date. example...
Today's Date is 12133. That's 12133 days since PICK has been 'born'. It then converts that into 03-20-2001 when you need to (By the way this is the way PICK was able to overcome all Y2K problems). Also, PICK has a function called Dictionary Item wich is a brand new concept for other, powerful ways of converting data.
If I'm telling you something you already know, I apologize, but I'd like more background if you could.
Basically what I'm saying is if you learn this unique version of BASIC, it's going to be impossible to use it until you understand the environment and that won't be simple.
I know that goes for all programming languages and OS's but my point is PICK is truly a unique environment. I haven't seen anything else like it.
