Hi jojimbo.
There is a tutorial on Hal, If you right click the Hal System icon usually in the lower right corner of your desktop toolbar, you should see tutorial there.
As far as actually teaching you how to write scripts is easy but would still take you a long time to be any good at it.
There will be meetings once a month in the forum for just that occasion of sharing scripts and functions in the chat meet, This may be of help to you.
As far as any custom scripts you desire within the limits of VBScript
is another thing I can help you with as a member of Ultra Hal Bot Enhancement Forum. That's what it's all about, Teamship teamship teamship.
I'm excited to see you on the board with us and hope to see you soon.
Best of wishes and grand new discoveries.
Jerry.
