### 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.
