[pdp-discuss] ta-iv question

[Richard Jones]

I'd like to try implementing my own learning algorithm, using the bp
code as a starting point.  I've built the latest pdp++ and got it
hooked up in my debugger, and have stepped through the code for all
the interesting parts.

For yucks, I added a new float data member to the BpConSpec class in
"bp.h".  It showed up in the "bp_TA.cc" file after make_ta, and
everything compiled and ran.

As I was building a new network in the app, however, I tried to edit
the BpConSpec to see if my new field was there, and it all ground to a
halt.  I suspect I must tell some part of IV about my new data member
so it can build the editor window correctly, but I'm not sure how.
Can someone point me in the right direction?

I've included the stack trace below my signature.

Many thanks.
