GOTO <Label> Command is now available. Labels are lines
in which the first non whitespace character
is a ":". The target of a goto is the first
matching label in the current do command
file which is encountered. Since labels
don't do anything else besides being the
targets of goto's, they could be used to
provide comments in do command files, for
example (":: This is a comment")
SET ON Enables error trapping for currently defined
traps (by ON commands)
SET NOON Disables error trapping for currently
defined traps (by ON commands)
RETURN Return from the current do command file
execution with the status from the last
executed command
RETURN <statusvalue> Return from the current do command file
execution with the indicated status. Status
can be a number or a SCPE_<conditionname>
name string.
