4 Text Output
Most ASTERIX applications which output data in ascii form do so using
a DEV parameter. The value taken by this character string parameter
determines the destination of the output data. There are five special
values for this parameter:
- TERMINAL, CONSOLE
- Either of these directs output to the terminal (or standard output
in UNIX speak). This is often the default choice. Using this
option means the output can be piped to
further UNIX commands, eg.

- PRINTER
- The system default print queue. The output
is spooled directly and leaves no work file
behind. See the 'Spooling' subtopic for
much more info on controlling spooling.
- NEWFILE, OLDFILE
- If NEWFILE is specified, then output is sent
to 'ast_print.lis' (but this can be overridden by
particular applications, spectral
fitting uses 'fit.op'). If OLDFILE is
specified then ASTERIX attempts to open an
existing text file for append access.
All of the above key words can be abbreviated to as few as one letter.
