Well, the C standard says that long must be ``at least'' 32 bits,
maybe more. To the best of my knowledge, gcc uses a 32-bit long
even on 64-bit systems, to maintain compatibility with old code.
This was true last I checked, a year or two ago.

Why oh why doesn't gschem --version DTRT?
Peter :-(
Does it mean that a change like in the attachment has any chance
in future gschem development?

Hello,
I'd like to simulate a very simple circuit, an active lowpass filter. But I
think I'm doing something wrong with my AOP, because ngspice cannot load the
netlist:
--
$ ngspice 78 - source ./spice.net
Circuit: * gnetlist -g spice-sdb -o spice.net lowpass.sch

Your ngspice lacks POLY() support. See

But if we limited everything to 2m, using unsigned integers, we'd
be okay with 32 bits. I'm not sure what you're saying here.
Having said that, I still want negative coordinates. So do we need
to limit things to 1m? Yuck.
He is saying that to avoid overflow
Internally the origin of the grid should go to the middle of the
board, but have the board translate the coords to physical of the
upper left, or even lower left. Make some folks happy about their y
decreasing or somthing or another.
This removes the loss from the other three quadrents of area

OK, but we have snap to grid, and grid will have units, and display of
coordinates. And arbitrary scale for output makes not

Yay, that was it ! Thanks a lot ! The plot in ngspice is now ok.
For anyone using port, you just need to modify the Port file in the
ports/release/science directory. Add

Close, but you missed to point out that a char is signed on my box.
It could as well be unsigned, but
