-file:
This specifies the parameter file read by dviout (cf. Q_S3).
When specified in the [System] of Property Sheets and set to be read at start-up, after the parameters are read from the Registry, this parameter file is read and overwritten.
When ^x is added at the beginning of the path name, it is replaced by the directory where dviout is installed. Likewise, ^w is replaced by the Windows directory.
When started, dviout looks for dviout.par or dviout.ini in the directory containing the dviout.exe. Failing that, it then searches the Windows directory.
The parameter file can include other files; the nesting can be up to seven levels.
