# File Menu

Open: Opens a RST2 results file and reads in the data. If one is available it also inputs the corresponding RSU file. The file name and data read from are appended to appropriate drawing menus. When you run out of memory a dialog will tell you.

> You may run out of memory for several reasons, in order of likelihood, (1) you have too many data either because your data files are very large or because you have too many files open simultaneously, (2) the size of the data set (i.e. the grid size of the study area) is too big, or (3) you may have too many files open. To solve (1) and (2) dispose of some data sets and try again. To solve (3) try studying a smaller domain or reducing the grid resolution in the simulations.

Difference: Opens 2 RST2 files and takes the difference between the variables selected. When data is displayed the difference between two values is shown (for instance if elevations are selected then the difference in elevations is shown).

> You may run out of memory for the same reasons as for the open operations

Dispose: Disposes of all data from the selected data file. All memory associated with the data file is recovered so that if you run out memory trying to visualise several data sets first try disposing of unnecessary data sets. In V1.0 dispose is not implemented because of bugs in the Windows '95 software packages use to develop VIEWER.

Statistics: Gives overall statistics of the selected data file (eg. size of the data file and min, max and mean for the various data sets).

Quit: Quits the program. The DOS window that was opened when the program started is automatically closed.
