aoutToBinDec is sent the input "tmp.o". aoutToBinDec will write to
standard output. The "|" is the pipe notation. The output of
aoutToBinDec is sent to the input of deflate. deflate's output is
sent to tmp.Z.

This command could be written like this,

aoutToBinDec < tmp.o > zhengbuaa
deflate < zhengbuaa > tmp.Z
del zhengbuaa

The extra file "zhengbuaa" is created. As well, it is possible for
the OS to run these commands in "chunks". So only 1k at a time could
be taken from aoutToBinDec and passed to deflate. If this happens,
you don't need as much disk space or memory. It is also possible that
things execute faster due to caching (on the host machine).

So it is not just to avoid typing...
