I'm already very experienced in programming in a variety of languages, so I don't require any help in those concepts.

What I'm finding confusing is that they don't seem to work as I would expect on this device.

For example, this is what I would expect to happen:

If (somevariable == false )
{
actions here ;
somevariable = true ;
}

Yet, those actions always occur.

So I tried this as a test:

somevariable = true ;
If (somevariable == false )
{
actions here ;
somevariable = true ;
}

And the actions still occur anyway.

What am I misunderstanding?
