Three different user-levels are maintained within the MIDAS system.
NOVICE (beginning MIDAS user)
USER (normal MIDAS user)
EXPERT (expert MIDAS user)
These user-levels are set via the command SET/MIDAS_SYS user=level,
e.g. SET/MIDAS_SYS us=EXPERT.
The level NOVICE is the default level assigned to you when getting into
MIDAS.
The following functions of the MIDAS system are affected by the user-level:
HELP facility:
Help text for NOVICE- and USER- level MIDAS users is limited to the
screen size of the terminal, i.e. you have to hit 
to scroll through the help text, if it is longer than single
screen size.
For EXPERT users the help text is typed out completely.
ERROR reporting:
For NOVICE- and USER- level MIDAS users the full error text is displayed.
For EXPERT users only one-line error messages are displayed.
CREATE/COMMAND command:
EXPERT users may create commands which override already existing MIDAS
commands (be careful ...).
All other users may only create new commands.
Note, there is no difference between the level NOVICE and USER, but this may change in a future release of MIDAS.
