ACL2-PC::DROP
(primitive)
   drop top-level hypotheses
Major Section:  PROOF-CHECKER-COMMANDS
Examples:
(drop 2 3) -- drop the second and third hypotheses
drop       -- drop all top-level hypotheses
General Forms:
(drop n1 n2 ...) -- Drop the hypotheses with the indicated indices.
drop             -- Drop all the top-level hypotheses.
Remark:  If there are no top-level hypotheses, then the instruction
drop will fail.  If any of the indices is out of range, i.e. is not
an integer between one and the number of top-level hypotheses
(inclusive), then (drop n1 n2 ...) will fail.
