reset - clear all variables of a given name
reset EXPR
reset
Generally used in a continue block at the end of a loop to clear variables and reset ?? searches so that they work again. The expression is interpreted as a list
of single characters (hyphens allowed for ranges). All variables and arrays
beginning with one of those letters are reset to their pristine state. If
the expression is omitted, one-match searches (?pattern?) are reset to match again. Resets only variables or searches in the
current package. Always returns 1. Examples:
reset 'X'; # reset all X variables
reset 'a-z'; # reset lower case variables
reset; # just reset ?? searches
Resetting "A-Z" is not recommended because you'll wipe out your
@ARGV and @INC arrays and your %ENV hash. Resets only package variables--lexical variables are unaffected, but
they clean themselves up on scope exit anyway, so you'll probably want to
use them instead. See my.
