[Groff] ms macro and PO (left margin)

[Ralph Graulich]

Hi,

I am converting the documents needing rotated text (see other thread) from
mm to ms. Carefully changed the document's setup, concerning setting the
corresponding number registers. However I can't set the PO (left margin)
to zero or any other than the predefined value.

For example:

-----
.nr LL 17c
.nr HM 2c
.nr FM 2c
.nr PS 9
.nr VS 9.8
.nr PO 0c
This is just some text for internal testing. Be prepared, as this text
has neither any special meaning nor making sense. You can read the whole
paragraph, but it will be pretty useless. Spend your precious time reading
something more interesting. It will be really boring, you have been
warned. In case you still want to read the whole text, you are welcome,
but I am sure you'll be pretty clueless about the deeper meaning of all
those words.

produces the same left offset no matter what value is used for "PO".

What am I doing wrong here?


Kind regards
