While the above is true and can be very useful, there is still a big
difference between this and the up arrow "history" on VAX/VMS systems. On
UNIX the command !number invokes the shell whereas on VAX/VMS you can bring up
the last command, modify it slightly and then hit return to invoke the
command. This is a very powerful and time-saving device, especially if you
are dealing with a typical GCG command line such as:
$gap/beg2=1/end2=32000/rev2/out=tseb.out/def tseb.gseq ghloc.gseq
