#### Input File Name

`Input_File_Name=`file | Sets input file name to file
`+I` file | Same as `Input_File_Name=`file

You will probably always set this option but if you do not the default input filename is `object.pov`. If you do not have an extension then `.pov` is assumed. On case-sensitive operating systems both `.pov` and `.POV` are tried. A full path specification may be used (on MS-DOS systems `+Ic:\povray3\mystuff\myfile.pov` is allowed for example). In addition to specifying the input file name this also establishes the scene name.

The scene name is the input name with drive, path and extension stripped. In the above example the scene name is `myfile`. This name is used to create a default output file name and it is referenced other places.

If you use "-" as the input file name the input will be read from standard input. Thus you can pipe a scene created by a program to POV-Ray and render it without having a scene file.

Under MS-DOS you can try this feature by typing.

     type ANYSCENE.POV | povray +I-
