|Getting Started with the SAS System Using SAS/ASSIST Software|
To invoke SAS/ASSIST software, follow these steps:
SAS/ASSIST Welcome Window
If this is not the first time that you have run SAS/ASSIST software, the SAS/ASSIST Start Menu appears.
SAS/ASSIST Start Menu
SAS/ASSIST Workplace Menu
A button is a graphical shape in a window that, when selected, results in an action. OK, Cancel, and Run are examples of buttons. The most commonly used buttons are described here:
|OK||accepts what you have entered in the window and takes you to additional windows to continue the task. In some cases, OK performs the task.|
|Cancel||cancels what you have entered in the window and returns to the previous window.|
|Goback||returns to the previous window.|
|Help||displays help for the feature in use.|
If you cannot find the item that you want to use in SAS/ASSIST software, you have two guides to help you:
The SAS System has extensive online help. You can get help for a particular window or general SAS software product help. To access the general SAS System help, follow this selection path:
|Help||SAS System Help|
|Help on SAS System Products||SAS/ASSIST||Using SAS/ASSIST|
To get help for a particular window, follow this selection path from that window's menu bar:
|Help||Using This Window|
|Using HTML Output|
SAS/ASSIST software can generate HTML-formatted output for reports and graphics. You can then view your output in an HTML browser, as in the following example.
Contact the SAS Support Consultant at your site for more information about HTML browsers available to you.
To generate HTML output with SAS/ASSIST software, see Setting Up HTML Output. This may have already been done for you; see the SAS Support Consultant at your site for more information.
|Using SAS/ASSIST Software with This Book|
In creating the examples and illustrations in this book,
we removed the date and time stamp from all output and disabled the Save Changes
dialog box that appears when you exit a task window. We recommend you do the
same so that your experience with SAS/ASSIST software will match the descriptions
in this book. This section describes how to apply these conditions.
To remove the date and time from your output, follow this selection path from the SAS/ASSIST WorkPlace menu bar or any task window menu bar:
|Edit||Page Headers||Print current date|
Note: This option is not applicable to graphics
output and is not available on graphics
To disable the Save Changes dialog box, the SAS/ASSIST user profile option Confirm changes is set to No. To set this option, do the following:
noand press ENTER.
|Creating the Sample Tables|
In order to perform the exercises in this book, you must create the sample tables. These sample tables are used throughout this book and can be used to learn to use the software. When you are using these sample tables, you can try any of the options in SAS/ASSIST software. You do not need to be concerned about harming the sample data. You can easily re-create the sample tables if, for example, you have altered them so that they no longer correspond to the SAS/ASSIST software documentation and tutorial examples.
|Tasks||Setup||File Management||Sample tables...|
Sample Tables Window
Create Sample Tables Window
Note: If you are re-creating sample tables (rather than
creating them for the first time), and you attempt to re-create a table that
is the currently active table in one or more SAS/ASSIST tasks, you get an
error message because SAS/ASSIST software does not let you re-create an active
table. To remove a table from active status, follow the directions in
De-Selecting an Active Table.
Create Sample Tables Message
|Deleting the Sample Tables|
If you no longer wish to use the sample tables, you can delete them.
|Tasks||Setup||File Management||Sample tables...|
Delete Sample Tables Window
Note: You cannot delete a table that is currently the
active table in one or more SAS/ASSIST tasks. To remove a table from active
status, follow the directions in De-Selecting an Active Table.
Deleted Sample Tables Message
|Frequently Used SAS/ASSIST Operations|
This section describes how to perform operations that
are common to most SAS/ASSIST tasks.
The task examples in this book refer you to this section when these operations
When a task example instructs you to select a table, follow these steps:
Select Table Window
The Select table window contains a list of SAS data libraries on the left side and a list of SAS tables on the right. If there is an active table, the table name appears in the Selected table field as a two-level name. See SAS Files for details about SAS naming conventions.
If the desired table does not appear in the list of tables, it either does not exist, is not in a library that the SAS System knows about, or was added to a library after SAS/ASSIST software was invoked.
When a task example instructs you to select a column, follow these steps:
Select Table Variables Window
The number of columns you can select is indicated above the Available list. In certain contexts, not all of the active table's columns are listed. For instance, when the software performs an action that requires numerical data, only numerical columns are listed.
Note: In certain tasks, you can select more than one
column at a time; in others, you can select only one column. If you can select
only one column, the Select Table Variables window
disappears when you select the right-arrow button, and the column name appears
in the task window. In this case, you do not need to go any further in this
To de-select a column, select it in the Selected list and select the left-arrow button to move it back to the Available list.
Note: If you want to select
all of the available columns,
you can select the double-right-arrow button to select them all
at once instead of selecting them one at a time.
You can clear task window selections by selecting New from the File menu. However, this action does not clear the Active Table selection or the Subset Data selection. The reason for this feature is that many users wish to use the same subset of the same data for multiple tasks. To clear the Active Table and Subset Data selections, follow the steps in this section. To clear only the Subset Data selection, see the instructions in the next section.
Note: These steps also
clear the other
You can clear task window selections by selecting New from the File menu. However, this action does not clear the Active Table selection or the Subset Data selection. To clear only the Subset Data selection, follow the steps in this section. The reason for this feature is that many users wish to use the same subset of the same data for multiple tasks. To clear both the Subset Data selection and Active Table, see the instructions in the previous section.
When you are finished with a task, you can either return to the WorkPlace menu or go on to another task:
|Exiting SAS/ASSIST Software|
To exit SAS/ASSIST software, return to the WorkPlace menu and select Exit. The SAS/ASSIST window disappears.
|Exiting the SAS System|
To exit the SAS System, use one of the following methods:
SAS Exit Prompt When Using the Menu Bar
Select OK to exit the SAS System.
BYEand press ENTER. The SAS System terminates without further prompting.
