8.5 - ( .po + .ll)The smallest possible printed left margin is 1/2", which you get when you set .po to 0. In general, 1/2" is added to any .po that you specify. The same 1/2" is subtracted from whatever .ll you specify.
Place the .po and .ll commands at the beginning of the section where you wish the margins to change. The change stays in effect up to the point where you place different .po and/or .ll commands.
An example might help illustrate this: To get 1" margins on both sides, place the following commands at the beginning of your document. (The i following the numbers stands for inches.)
.po .5iThese were derived by:
.ll 7i
.po = (desired left margin - .5) = .5 in this caseYou would then highlight these commands with the mouse cursor, and select FormatNote from the Region menu card.
.ll = (8.5 -desired right margin - .po) = 7 in this case
Another useful fact that should be noted is that if you use .po and .ll with no arguments, the default values are returned.
