Thanks to those who replied to point out a gross stupidity on my part - the example I gave wasn't a legal LiveCode statement. I was too tired to notice. Sorry for the waste of bandwidth. I found the response of the message box mysterious but at least I'll recognise it next time.
My real script did have two problem but they were quite different, and might be of interest. 1. I had constructed a Windows-style path with "\" characters to fit in with a small VB script I wanted to run. This does work in some contexts, but not in this one: in normal circumstances (but not AFAICS in VB scripts) LC looks after the change from "/" to "\". I forgot that it was this path in the variable I was testing. It gave a strange result, but the obvious answer is "don't do it". 2. The form of my 'if' condition was if there is not a file myPath &"/" & myfilename it turns out that the 'there is no' statement doesn't construct the string before the evaluation: you have to ensure the evaluation of the string by putting it in brackets as in if there is not a file (myPath &"/" & myfilename) There is an obscure warning about this in the dictionary: "The there is no operator is implemented internally as a function, and therefore has lower precedence than other operators". So it's a precedence issue.
