p.map.new

When using the grid command within p.map.new, Im getting
the follow error when I try to control the font size:

ERROR: textsize illegal : 200

The file looks like this:

grid 500
pattern notick
masked all
width 1
color black
numbers 2 black in
numbersbg white
textsize 200
end

Can anyone help me get a normal grid on my maps with control
of the fontsize?
