 In other words, it is what I thought it is. However, most versions of
COMMAND.COM (indeed,all of MS,DR,PC and PTS I ever used) also keep only
a small part of them permanently in RAM, but reload from disk instead: 
COMSPEC= path if set, if not, SHELL= path and if nothing else, from the
boot disk. This is slower than from XMS but not by much if COMSPEC= points
to a ramdisk. I always thought non-xmsswap versions of FreeCOM also behave
this way. Don't them ? If not, do you know why ?
