Browsing through the help files I came across a command 'Clear'. However, it isn't actually documented anywhere in the help file. The usage was with structures, but I was wondering if this can be used to clear any variable?
I keep getting a compiler warning that I've not initialised a Char array. I was wondering if I could use Clear RxBuf rather than a for...next loop?
What does 'Clear' do?

Re: What does 'Clear' do?
'Clear' sets the variable to zero, and works with pretty much anything... variables, structures, arrays, etc.
For an array (or structure) it zeros each element and should be faster and use less code than using a for/next loop.
When used with a string it works a bit differently. For them it just sets the first char to 0, which gives you a null string.

Forgot to mention...
Clear is documented in the language reference pdf http://www.sfcompiler.co.uk/downloads/SFManual.pdf
There's probably some other nuggets in there that aren't in the help file (and vice-versa)
