Guy,

To get a:

Set a to 0
Interate through each line subtracting the horizontal offset of insertion point 1 from the horizontal offset of insertion point -2 of each line.
Compare result with a; if larger, set a to it. At the end, you have a.

To get b:

Set justification of first paragraph to full justification. Set left and right indents and first line indent of the paragraph to 0.
Subtract the horizontal offset of insertion point 1 of the first line from the horizontal offset of insertion point -2 of the first line. That's the value of b.

Reset the first paragraph's justification and first line indent (actually, if you have first line indents you might get the wrong result) and then set the right indent of all the lines to (b-a)/2.

I am not at all fluent in VB, so this is the best that I can do for you.

Dave
