DESCRIPTION

This package provides a forward-compatibility implementation of Tcl 8.6's throw command (TIP 329), for Tcl 8.5. The code was directly pulled from Tcl 8.6 revision ?, when try/finally was implemented as Tcl procedure instead of in C.

::throw error_code error_message
    throw is merely a reordering of the arguments of the error command. It throws an error with the indicated error code and error message.

EXAMPLES

    throw {MYERROR CODE} "My error message"
