SET.SPEED Enable/disable the ability to set the monitor speed from the
manual control pendant. Default is enabled.
TRACE Enable/disable a special mode of program execution in which
each program step is displayed on the system terminal before it
is executed. This is useful during program development for
checking the logical flow of execution (also see the DRY.RUN
switch). Default is disabled.
UPPER Determines whether comparisons of string values will consider
lowercase letters the same as uppercase letters. When this
switch is enabled, all lowercase letters are considered as though
they are uppercase. Default is enabled.
