Extending the Display Manager in SAS

The commands below can be used to expand the Display Manager in SAS.

Command Description
vt &syslast.; Add to keys, e.g. F5. This opens a Viewtable with the latest run dataset/view.
next viewtable:; end; Add to keys, e.g. F9. Then F9 closes the last used table (that is open). Can close all views with multiple F9’s.
odsresults; select all; clear; wpgm; Add to keys, e.g. SHIFT F1. This key bind clears all SAS “results” and returns to the program editor.
log; clear; wpgm; Add to keys, e.g. F4. Clears log without having to highlight the log window. Returns to the program editor.

 

Using SAS display manager (DM) for data exploration

The display manager (also known as DM) in base-SAS can be used for data exploration. For this demonstration the dataset sashelp.class will be used. Now sashelp.class is easy to get an overview of because it only has five variables. But if you have a lot of variables then some kind of data exploration/data manipulation might be handy.

Let’s say that you would like to take a look at the varable Age. In the DM you will write keep age.

This will result in a displaying of the data only showing the variable age. Now you would like to have all the other variables shown but keep age as the first variable being displayed. This can be done writing the command unide _all_ in the DM.

Now all the variable will be shown with age as the first variable.

It is also possible to keep multiple variables. In the DM you can eg. write keep ‘height weight’. Remember that when keeping multiple variables you will have to write the variables in ‘ ‘.

Now only these variables will be shown.

You can again unhide the rest of the variables writing unhide _all_ this will keep the height and weight variables as the first variables being shown.
