Repeat a .SUB file "nn" times. Used in two "phases":
(1) type "REPEAT nn" to set things up (just stores a count
at 8.
(2) Place "REPEAT" in your .SUB file immediately before a
line re-submitting the original file.
EX:
First, type
REPEAT 5
Then have your submit file be:
blah
blah
blah
repeat
submit foo
When repeat executes with no operands, it decrements the
count at 8, and if 0, erases $$$.SUB.
