the command line above IS in the 'main' variable space - typing 'common
..' puts those variables in 'main'. You haven't lost any memory, since
those variables are there anyway, albeit invisible.

If you do need to get memory back, just set any (large) arrays in the
common block to be smaller. This doesn't always work, but that's another
story.....
