There are some cases when many people are sharing one machine such as under Windows NT.
1. Create a dviout.par file in the directory containing dviout (or a Windows directory) and specify default Parameters in that file. (After set various parameters in the property sheet, then edit them in "Option -> Non-default parameters" and finally output them to a file by output of parameter setting.)
2. Some of the users might want to change parameters from the default.
In such a case, change the parameters in "Option -> Setup parameters," and save in the Registry.
Then select the [REGISTRY] sheet, mark the + to the parameters he wants to change (at first, all the item on the table might be marked with +'s. Then press the [All clear] button to clear all the +'s. After that, mark the items +'s he wants to change.), and press the save button.
dviout first reads the parameter file, followed by reading the Registry settings. Then the parameter values are overwritten with values in the Registry.
