Ben, I found the Scheme demo and tried it again, briefly. The file requester
seemed to work fine, and I remember now that it was working for me previously.
However, it definitely did not work the first time or two. A friend also had
difficulty with it, so I'm not dreaming. I am now _thinking_ that this copy
might be your second upload of the program. Is that possible? If there were
in fact two uploads, then maybe the first one had problems, but I think I
erased it. If there was only one upload, then I'm not sure what is happening.
I'll certainly let you know if it happens again. The symptom was simply
inaction – click on all the gadgets and fields and nothing happens. Don't worry
about it until/unless I can repeat it.
By the way, can you list some of the present and/or planned improvements you
alluded to (both in Scheme and the future Scheme+)? Also, does Scheme use its
own netlisting format, or is it compatible with anything else? On the last
digital chip I did, I could have used a capture program that listed in HILO3
format – that's what the other company's software used, though I really don't
know how universally understood it is. Any possibility of getting Scheme to
write Spice (analog simulator) input file format (maybe with modification
ability to support different versions or enhancements)? Just exploring some
possibilities.
As far as helping me understand the Scheme demo… Don't laugh, but I'd like
you to explain precisely how to locate and/or define the "grab point" of a
device. I am able to move things around, but haven't yet picked up the system
correctly, because the objects often move somewhere different than I had
planned. Perhaps others don't have these problems with your demos, but I must
say that some quick docs would help me (even more than a bunch of sample
drawings) – and I'm usually pretty good at picking up such things. You write
lots of impromptu messages on CIS, so it should be cake for you to whip up an
explanation of something you _really_ understand (grin).
Lastly, see my reply to message 91885 – any comments?
