As in: 'pragma Volatile( ... );' ??  I have used 'pragma Pack(..);' to buy
space at the expense of CPU time in a mission log kept on a solid-state device
of modest (<100 MBy) capacity.  This had a direct impact on the length of
test our equipment could monitor.  I have more frequently used 'pragma Pack'
for inter-processor communications, such as to load and unload packetized
communications records.  Although I have not had to pack data to conserve
RAM space, I couldn't rule this out for other users.
