# reset

## Synopsis

```perl
reset;            # reset all ?? in current package
reset 'a-z';      # reset ?? in variables matching range
```

## Description

Resets `??` (one-shot match) operators so they can match again.

The `??` operator matches only once between calls to `reset`.
Without an argument, resets all one-shot matches in the current
package. With a character-range argument, resets only those in
variables whose names fall within the range.

This is a deprecated and rarely used feature. Returns 1.

**Implementation status:** Stub (no-op). PetaPerl does not
currently track `??` match state.
