# Output of Parameter Setting

You can obtain a list of all the parameter values in .par format which dviout can refer by selecting "Option->All Parameters". By selecting "Option->Non-default Parameters", you can obtain a list for only the parameter values which differ from the default. (You can copy the list to the clip board or output to a log file.)
On the other hand, selecting "Option->Choose Parameters" and pushing [Save], the current parameter values are saved in a file with a title and a comment and will be read later setlecting from the list.
Once you save the parameter list to a file, dviout can read the file by selecting "Option->Read Parameters". If the file is in the directory containing dviout.exe with the name of dviout.par, dviout can find the file when start-up and reads the parameter values.
This parameter list output function would be useful when you want to save the current parameter values, check the parameter specifications, copy the parameters to other computers, or creat the common default Parameters for machines shared by many users.
