load/dump is a godsend!!!! I am also in process of trying to learn MacApp
from C++... I got the ETO disk with C++ beta 4 (you need beta 4 to do
load/dump).  I tried compiling the Nothing program on my IIx... the first
time, it was 4-5 minutes.  I made a small change (changed the size of the 
boarder)... compile time dropped to about a minute.

To use it, you need to mod your makefile... the release notes explain 
how, and I don't have them in front of me.  Basically you add in a line
to compile the headers, and a compiler option will cause this to dump.
then all other compiles have an option added to do a load.  You also
need to add a line to link a .o file that the dump generates.

You can.  Just put MPW in the background.  It will keep chugging along.
If you want to play in MPW while it is compiling, you need to make a
new copy and run two copies of the shell (see the docs for v. 3.1)
