There isn't any good way to do that, period. When it comes to inheritance,
variables are only inherited from a master channel to a slave channel. In the
case of the Macro operating within the Dial, that Macro is occurring
exclusively on the slave channel. You cannot directly set variables on other
channels (for obvious race-condition reasons).
However, you could do this in a roundabout way, either by using a database or
by using shared variables in trunk. You'd need to first set (in the master
channel, before the Dial) an inherited variable containing the name of the
master channel, i.e. Set(_masterchan=${CHANNEL(name)}), then use that
inherited variable to set the shared variable in the master channel from the
slave channel, i.e. Set(SHARED(foo,${masterchan})=...). Finally, you would
be able to access the shared variable in the master channel with
${SHARED(foo)}. Again, the SHARED function is only available in trunk at this
time, although you could probably backport it to 1.4 with minimal trouble.
