.SH DESCRIPTION
.CO Cont
exits from a break level and continues execution of the
interrupted program.
.PP
If the break level was created by the
.CO stop
command or by the user entering a \*(^C during execution,
.CO cont
is called without an argument.
A shortcut for doing this is to enter a \*(^D at the break level.
.PP
If the break level was created due to a warning or error,
.CO cont
can be called with a continuation value as its argument.
The type of the continuation value is specified in the
error or warning message when the break level is generated.
(The message can be redisplayed with the
.CO whereami
command).
.CO Cont
substitutes the continuation value for the expression
which caused the error or warning when it
continues execution.
.PP
.CO Reset
returns to a previous break level without continuing execution from
the current break level. 
.PP 
If
.CO reset
is called without an argument (or if
.AR level
equals
.VL 0 ),
the user is returned to the top level of the environment.
If
.AR level
has a positive value, the user is returned to that break level.
If
.AR level
has a negative value,
the user is returned the specified number of break levels.
.SH BUGS
Not all errors can be continued from by supplying a
continuation value to
.CO cont .
