where dataset is a dataset name.
If the dataset name is not entered as part of the command, then the first screen to appear will prompt for a dataset name. A dataset name consists of up to 8 characters. This name is used as the beginning part of the names of many of the files that will be created. These file names are constructed using the dataset name followed by a dot plus a 2- or 3-character suffix. Some examples are:
If a dataset exists, it is read. If a dataset is new, the next screen prompts for confirmation that it is acceptable to create a new dataset. If so, the following screen prompts for the grid size: the number of layers, rows, and columns. These grid size values cannot be changed within MFI after this screen is accepted, so be careful to specify them properly. If it is not acceptable to create a new dataset, MFI stops without doing anything more. MFI stops at this point because it is assumed that the user intended to enter the name of an existing dataset, but may have forgotten the name. The user can then take whatever steps are necessary to determine the correct name and restart MFI.
