Hi All, Many Thanks for your kind words, but remember that this is just an updated version of Ian McPhail's stack SVGL: http://livecodeshare.runrev.com/stack/112/SVGL I posted a small update of SVGL (Not SVGL + Gradients) in this forum thread:

intersection point of two graphic line segments

I just want to run an idea by list members. I am looking at creating “overpasses” inserted into one grc line segment over another where they cross. I can use intersect to determine if any (newly created or moved) lines cross any other(s) already existing. However, that doesn’t tell you where

Ha, caught me being lazy. For loops like repeat with i = 1 to fld 1 there is (almost) no difference -- the field gets referenced one time at the start and that's it. But since I was lazy about how a loop with "step 2" in it would exit, I was slower. Thanks! gc On Wed, Nov 11, 2015 at 7:34

Re: 'Quit' mystery

The dictionary says this (from LC 6.7.5): In standalones, some care is needed to ensure you receive the *shutdownRequest* message if your application uses multiple stacks. The most reliable approach is to install a library stack or backscript to handle the message when your application starts up.

Re: Calculating the sum of a *lot* of primes

Interesting challenge, and puzzling crashiness. As a first thought, making the bAdd function private might have some speed advantage - but since the message path isn’t very complicated in this example, it might not be a lot. I’m not sure how many primes are involved, but I think its lots, as
