Yes! This would be nice, but also the other way aroud: I need HPGL
format as output from VEE.
At this moment I use a 'hand-made' headerfile which includes the grid
I need, and I append my data and comment to it. It works, but is
inflixible with respect to the grid, and clumsy to get good axis
information in the picture.
And it would be fine to be able to get this info back in VEE to
display.
It sounds reasonable to have a good interface between HPvee and HPgl
from HP itself, isn't it?.
Any information on both directions I would appreciate
With kind regards,

No ... I think you might want to get a conversion utility like HIJAAK and
convert them to BMP format and then display them in that fashion.
If you have other questions, let us know.

from and who it is intended for, as well as providing adequate return-path

as someone pointed out, the Internet currently is about as reliable as the
Russian phone system.
