)set output fortran

--------------------------- The fortran Option ----------------------------

 Description: create output in FORTRAN format

 )set output fortran is used to tell FriCAS to turn FORTRAN-style output
printing on and off, and where to place the output.  By default, the
destination for the output is the screen but printing is turned off.

Also See: )set fortran

Syntax:   )set output fortran <arg>
    where arg can be one of
  on          turn FORTRAN printing on
  off         turn FORTRAN printing off (default state)
  console     send FORTRAN output to screen (default state)
  fp<.fe>     send FORTRAN output to file with file prefix fp and file
              extension .fe. If not given, .fe defaults to .sfort.

If you wish to send the output to a file, you must issue this command
twice: once with on and once with the file name. For example, to send
FORTRAN output to the file polymer.sfort, issue the two commands

  )set output fortran on
  )set output fortran polymer

The output is placed in the directory from which you invoked FriCAS or
the one you set with the )cd system command.
The current setting is:  Off:CONSOLE

)set output tex

----------------------------- The tex Option ------------------------------

 Description: create output in TeX style

 )set output tex is used to tell FriCAS to turn TeX-style output
printing on and off, and where to place the output.  By default, the
destination for the output is the screen but printing is turned off.

Syntax:   )set output tex <arg>
    where arg can be one of
  on          turn TeX printing on
  off         turn TeX printing off (default state)
  console     send TeX output to screen (default state)
  fp<.fe>     send TeX output to file with file prefix fp and file
              extension .fe. If not given, .fe defaults to .stex.

If you wish to send the output to a file, you must issue this command
twice: once with on and once with the file name. For example, to send
TeX output to the file polymer.stex, issue the two commands

  )set output tex on
  )set output tex polymer

The output is placed in the directory from which you invoked FriCAS or
the one you set with the )cd system command.
The current setting is:  On:CONSOLE

)set output script

---------------------------- The script Option ----------------------------

 Description: display output in SCRIPT formula format

 )set output script is used to tell FriCAS to turn IBM Script formula-style
output printing on and off, and where to place the output.  By default, the
destination for the output is the screen but printing is turned off.

Syntax:   )set output script <arg>
    where arg can be one of
  on          turn IBM Script formula printing on
  off         turn IBM Script formula printing off (default state)
  console     send IBM Script formula output to screen (default state)
  fp<.fe>     send IBM Script formula output to file with file prefix fp
              and file extension .fe. If not given, .fe defaults to .sform.

If you wish to send the output to a file, you must issue this command
twice: once with on and once with the file name. For example, to send
IBM Script formula output to the file polymer.sform, issue the two commands

  )set output script on
  )set output script polymer

The output is placed in the directory from which you invoked FriCAS or
the one you set with the )cd system command.
