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. Only resets 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 ?one-time? searches
"A-Z" is not recommended because you'll wipe out your
@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".
