how to record bond exchange w/o basis change

[Larry Evans]

My broker changed shares of one bond(call it bondA),
with another(call it bondB) 1 for 1 in middle of 2014.
I could record the exchange as sell bondA and buy bondB
with the proceeds; however, wouldn't this require
capGains to be calculated for bondA and then a new basis
for bondB recorded for middle of 2014?

How can GC handle this?
