SAS for MS Windows98
- SAS may be launched by following these steps:
 | Click on the Start button
 | Find the Courseware Applications menu
 | Find the Statistical Apps menu
 | Select SAS V8 |
| | |
Use the Help menu or the F1 function key to obtain help on SAS.
Three windows are available, one for editing SAS programs and two others
for viewing log and output results from running those programs. Use the F3
function key to execute the code in the program editor window. You may also
use the Submit icon or the Submit menu selection from the
Locals menu. The log window will contain error messages and notes
on the execution of that program while the output window will contain the
results of executing the individual PROCs within that program.
After you execute code in the program window, that window is cleared by
SAS so that you can type and execute further code segments if you want. Use
the F4 function key, to reclaim code that you just ran. You may also use the
Recall Text menu selection from the Locals menu. Be careful,
you may accidentally generate multiple copies of the program, combined into
one, if you issue this command multiple times.
SAS also provides several menus for your use. Usually, you click the left
mouse button (LMB) to select an item from a menu, including the main menu bar
at the top of the SAS screen. Sometimes, depending on how SAS is installed,
you have to click the right mouse button (RMB) within one of the three types
of windows to pop up a menu for manipulating the contents of that window. This
is assumed in all descriptions below, but the menu may not need to be
popped-up, depending on how your installation.
For example, it is possible to cut and paste or delete portions of the
window contents. First mark the appropriate portion of text. You can do this
by dragging the mouse over the portion of text to mark while holding down the
LMB or by moving the arrow keys while holding down the shift key. To delete
the marked text, hit the delete key. To cut or paste the marked text, click
the RMB to bring up the pop-up menu and then click with the LMB to select the
Edit option and then the appropriate sub-menu item.
To move around in any of the windows, use the arrow keys to move one
position left and right and one line up and down, the Page Up and Page Down
keys to move a whole page at a time, the left and right arrow keys together
with the CTRL key to move left and right one word at a time, the Home and End
keys to move to the beginning and end of the current line, and the Page Up and
Page Down keys together with the CTRL key to move to the beginning and end of
the window. For the log and output areas, you need to use Page Down or Page Up
to change the page since the up and down arrow keys wrap around to the bottom
and end of the current page for these windows. However, the up and down arrow
keys will change the page within the program window. Use the Insert key to
toggle between type-over and insert modes for data entry. You will notice that
the cursor covers the whole current character position while in type-over mode
and is a line at the front of the current character position in insert mode.
To load, print, or save the contents of a window, click the RMB to bring
up the pop-up menu and then click the LMB on the File option. Use the Open
option to load a file into the window, the Print option to print out the
contents, and the Save As option to save the contents to a file. Be careful if
you use the Save option instead of the Save As option. The Save As option will
always request a file name and so you can determine where it will be saved.
The Save option will write to the current default file. However, the default
file may be a temporary file and so you will lose it when you exit from SAS,
or even worse it may be some other file that will accidentally be destroyed
(hence the need for a backup).
After you have coded and tested a program for one of the class
assignments, first clear the log and output windows, if not already cleared,
and then run your SAS program for printing out the results to turn into class.
It is important to clear these areas before running them for printing
purposes since the results of the execution of SAS code are merged together
with the previous contents of these windows. After running the program, recall
it, print out the contents of each of the three windows, and submit all these
printouts in class on the due date. |
