This will iterate internally over the elements of the array called _arrayName_ in array-iteration order \(i.e., the same as that used by the other **array** subcommands\), setting the variable _keyVar_ to the name of the element and the variable _valueVar_ to the content of the element before evaluating the script _body_. The result will be the empty string \(excepting errors, **return**, etc.\) and any contained **break** and **continue** will have their normal interpretation as loop control operations. # Implementation Branch: `tip-421` (Code is also available [here](https://github.com/flightaware/Tcl-bounties/issues/12) within a comment, but that is _not_ the definitive version.) |

The result will be the empty string \(excepting errors, **return**, etc.\) and any contained **break** and **continue** will have their normal interpretation as loop control operations. Modifying the array while this command is iterating over it will make the **array for** command terminate with an error once the current execution of _body_ finishes. # Implementation Branch: `tip-421` (Code is also available [here](https://github.com/flightaware/Tcl-bounties/issues/12) within a comment, but that is _not_ the definitive version.) |
