Hello,

I think you are almost right.
Shareware means:
You can give it

to anybody, who can try it, thats why SHAREware. Usually there is no time

limit.
But often the programmers set a  time limit to their programs, and

they say: That program is shareware.
They are not correct

Hi,
The webpage pretty clearly sets it out, but let me give a few

examples.
Shades of Doom and Tank Commander are either trial or shareware

games.  You can try them out, but the author has disabled certain features. 

However, if you decide to purchase the game, you get an unlock code which

will transform your trial copy into the full product, with no

limitations.
Super Liam Demo is clearly a demo.  Although the game isn't a

concept demo or beta in that the full game has been produced and is

available, the SL demo has features disabled and there's no way to turn it

into the full product through use of an unlock code.  You must download the

full version which, by the way, can not be played as a demo.  Personally,

I'd have made the full version work as a demo if not properly

unlocked.
Jayson.
