There are 2 parameters which control how the whole PSS application appears to the user, without being specific to the source parameterisation process. These are EXPERT and DEV.
The purpose of EXPERT has already been noted, but is repeated here for completeness. EXPERT is a logical keyword which is prompted for unless specified on the command line. Its default value is propagated from one invocation of PSS to the next. It toggles the prompting of those parameters which are essentially fine tuning the operation of PSS, ie. those for which PSS can make sensible guesses. Obviously, such things as output file names do not fall within this category.
The DEV parameter is a standard ASTERIX parameter, described fully
in the online help (Ref 5,`` User Interface,Ascii Output"). Only data
pertinent to the output data products can be redirected by this parameter.
Thus, the psf enclosed energy tables are always sent to the user terminal
and not to whatever device has been selected using DEV. In PSS this
parameter has a hidden default of TERMINAL, which must be overridden
either explicitly on the command line or by forcing parameter prompting using
the PROMPT keyword.
