I put the same thing in an LC 'shell' command and got a runtime error (Handler: can't find handler). I guess this is because in the Terminal context, the shell recognised the program I was calling ('convert' - it's dear old ImageMagick) but within my prog and the LS IDE it didn't. What do I need to do to get 'my' shell to be able to invoke the same apps that the raw terminal interface can? My guess is that it's something to do with a context variable like LS's defaultFolder, but I just don't know how to get there. Can anyone explain?

Graham, post the exact code you're trying to make work using Livecode's 
shell() function so it can be debugged. The shell function should have 
access to any command the terminal has access to.

Best,

Warren
