<p class=MsoPlainText><b><font size=2 face="Courier New"><span lang=EN-NZ

I have never come across this limitation, although metapost usually logs
messages of seeming complaint. I inquired on the forum years ago, and one
of the Martin's or Stacho assured me that it should never actually run out.
Not sure if I have ever plotted 66km of centreline? I have probably come close.<o:p></o:p></span></font></b></p>

<p class=MsoPlainText><font size=2 face="Courier New"><span lang=EN-NZ

very useful. I add each survey as it becomes available. It is then in
the outputs as a reminder to draw the scraps! Further - you can
differentiate the flags that apply to each survey shot with colour and line
style.<o:p></o:p></span></font></b></p>
