If you read in a list of "moves", and save them in a sequence, 
you might have a sequence like:
{ {11,15},{15,20},{20,22},{22,24} }  

where 11 is the first source location, and 15 the first destination, 
and so on. Let's say you name this sequence "move".

To point to which move you are currently interested in, you need to 
declare an integer variable: call it anything you want. For example:

integer current

current = 1

now,  to refer to the first move on the list of moves, you'd say:
move[current] -- which is the same as saying move[1].
or {11,15}

The next move on the list would be move[2], so, 

current += 1 -- now current holds the value 2
move[current] -- same as move[2], which is:
{15,20}

So, you use the pointer into the list of moves to select the move 
you're interested in, and send that move to your routine which 
handles ..erm... moves.

You can get Judith's IDE from RDS' Recent Contributions page, or directly from
http://www2.txcyber.com/~camping/judith.html
Be sure you have the correct version of Win32Lib to go with that.
