/out (Visual Basic)
Specifies the name of the output file.
Specify the full name and extension of the file to create. If you do not, the .exe file takes its name from the source-code file containing the Sub Main procedure, and the .dll file takes its name from the first source-code file.
If you specify a file name without an .exe or .dll extension, the compiler automatically adds the extension for you, depending on the value specified for the /target compiler option.
