FILE
This command is used to specify a data file to be read When a data file
is specified it will be opened, and the names of the variables in the
file will be displayed as buttons at the bottom of the main widget.
Widget:
- Select "Data File" from the "File" menu
A file selection widget will
appear. You will see boxes for the current file filter, the
subdirectories of the directory specified by the file filter,
and the files specified by the file filter. There is also a
type-in box if you want to type in your commands.
To use the file filter, move the mouse pointer to the Filter
type-in box, and type in your choice. Press <RETURN>
after you
have finished typing.
You can use the filter to screen out all but the files that you
prefer to see. For example, if your data files all are of the
form model_1000.dat, you can set the filter to screen out all
other files by using model*.dat as the filter.
To select a directory or file, move to the appropriate box and
double-click on your selection. If needed, use the horizontal or
vertical scroll bars. Note that as you change the filter
or select new directories or file names, the changes are
reflected in the Selection type-in box.
When you have made your selection the specified data file
will be read, and field buttons
will appear at the bottom of the main widget.
- See MULTIPLE_READ for an explanation
of the dimension buttons at the bottom of the file selection widget.
The default is "NONE" - the data is all in one file.
