These are the parameters you can feed the programs from a command prompt, very useful for booting them with specific instructions and getting into the game quicker. These parameter lists are taken directly from the programs, with a few edits. If you want to view the most up-to-date lists for EDuke32/Mapster32, just open them from a command prompt with the parameter -?, -help, or --help. Note that in EDuke32/Mapster32, the forward slash (/) can be used interchangeably in place of the hyphen (-) for all parameters, but in the original game the syntax must appear strictly as shown.

Build Parameters
Usage: BUILD [FILE]
| <file.map> | Load map <file.map> in editor* |
* These parameters can also be used to load an official map directly from the DUKE3D.GRP file (provided a map file with the same name does not already exist in the game's root directory). If the map is being loaded in an editor, it could then be saved to the game's root directory. However, it is strongly recommended to extract the maps using KEXTRACT instead, since the save operation of any map editor is virtually guaranteed to modify the map.
