Usage: FOR (begin, expression, iter) {.....}

Causes the commands enclosed in the {} block to be executed in 
the following fashion:

	1) The commands in the "begin" portion are executed first
	2) The "expression" is evaluated
	3) If the "expression" is false, exit the command
	4) If the "expression" is true, execute the commands within
		the {} block
	5) Execute the commands in "iter"
	6) Go to step 2

Example:

	FOR (@x=0, x < 5, @x++) {echo X is now $x}

would output:

X is now 0
X is now 1
X is now 2
X is now 3
X is now 4


This command is equivilant to the following WHILE construct:

	begin	
	WHILE (expression)
	{
		....
		iter
	}
