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. 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 ?? searches
Resetting "A™Z" is not recommended since you'll wipe out your
ARGV and ENV arrays. Only resets package variables™™lexical variables
are unaffected, but they clean themselves up on scope exit anyway,
so anymore you probably want to use them instead. See my entry.
