You can run ORTEP in either of the 3 ways:

                $ ORTEP                ........... [1]
     or         $ ORTEP HELP           ........... [2]
     or         $ ORTEP P1             ........... [3]

where P1 can be passed with the name of file to be plotted
with the following optional positional qualifiers:

1) Operation mode qualifier:   /M=keyword

   The valid keywords for /M are

     PLOTTING ------------ plot on screen right away.
     HARDCOPY ------------ make a hardcopy right away and quit.

   Additional information can be entered for hardcopy mode in the format:

     		/M=HARDCOPY(KW=n,...)

   where the valid "KW=n"s are

     HC=n ------ hardcopy color (0<=n<=1).
     PF=n ------ paper feed upon finish (0<=n<=1).
     RO=n ------ rotation for vertical plot (0<=n<=1).
     PT=n ------ paper tray loaded (0<=n<=1).
     PS=n ------ plotter pen speed code (1<=n<=9).
     IM=n ------ plot output mode (1<=n<=4).
     TY=n ------ hardcopy device type (0<=n<=3).

   and overrides the hardcopy attributes in the parameter file.

2) Hardcopy destination qualifier:   /O=destination

     This qualifier overrides the /M qualifier and
     hardcopy mode is automatically established, where
     the distination can be a file-specification or an
     address of a plotter device.

3) Parameter file qualifier:   /P=file-spec

     Designate the parameter file (where applied)
     which overrides the default parameter file.

All keywords can be abbreviated down to their first 3 letters.
Uppercases & lowercases are equivalent.

Examples of input command lines:

$ ORTEP JUNK.TEP
$ ORTEP JUNK.TEP/M=HARDCOPY(TY=2,HC=0)/P=COMMON.PAR
$ ORTEP JUNK.TEP/O=NODE::PLOTTER:
