Synopsis
reset expr
Description
Used at the top of a loop or
in a continue block at the end of a loop, to clear global
variables or reset ?? searches so that they work again.
expr is a list of single characters (hyphens are allowed
for ranges). All scalar variables, arrays, and hashes beginning with one of
those letters are reset to their pristine state. If expr is omitted,
one-match searches
(?
PATTERN
?) are
reset to match again. The function resets variables or searches
for the current package only. It always returns 1.
Lexical variables (created by my) are not
affected. Use of reset is vaguely
deprecated.
