NAME
reset, setexit - execute non-local goto
SYNOPSIS
setexit( )
reset( )
DESCRIPTION
These routines are useful for dealing with errors and inter-
rupts encountered in a low-level subroutine of a program.
Setexit saves its stack environment in a static place for
later use by reset.
Reset restores the environment saved by the last call of
setexit. It then returns in such a way that execution con-
tinues as if the call of setexit had just returned. All
accessible data have values as of the time reset was called.
The routine that called setexit must still be active when
reset is called.
