Using SAS Studio :: SAS(R) Studio 3.3: User's Guide

About Using SAS Studio

When you sign on to SAS Studio, the main SAS Studio window appears with a blank program window so that you can start programming immediately. You also have access to all five sections of the navigation pane.

Note: To sign out of SAS Studio, click the Sign Out button on the toolbar. Do not use the Back button on your web browser.

The main window of SAS Studio consists of a navigation pane on the left and a work area on the right. The navigation pane provides access to your folder shortcuts and folders, your tasks and snippets, the libraries that you have access to, and your file shortcuts. The Folders section is displayed by default.

The work area is used to display your data, code, tasks, logs, and results. As you open these items, they are added to the work area as windows in a tabbed interface.

Using the Navigation Pane

About Using the Navigation Pane

You can expand the sections of the navigation pane by clicking the section that you want to view.

Working with Folders

The Folders section of the navigation pane enables you to access files and folders from the following locations:

your SAS server
any remote FTP server on which you have an account

Note: SAS Studio supports only FTP servers that use a UNIX style directory listing. Filenames in Asian languages are not supported on the FTP servers.

The type of SAS Studio deployment you are using determines the folders and files you can access from the Folders section and the locations to which you can assign libraries.

If you are running the SAS Studio Mid-Tier (the enterprise edition) deployment, then your My Folders location is your home directory on the remote SAS server.
If you are running the SAS Studio Basic deployment, then your My Folders location is your home directory on the remote SAS server. The folders list also includes the root folder of the UNIX file system on the remote SAS server.
If you are running the SAS Studio Single-User deployment, then your SAS server is your local machine. Your My Folders location is your home directory on your local machine. The folders list also includes folders for your desktop, documents folder, and all currently mapped drives.

For more information, see SAS Studio: Administrator's Guide.

You can open files that are saved on the SAS server or the FTP server, such as SAS program files or program package files. You can also open SAS tables that are saved on the SAS server.

Note: You cannot open SAS tables from a remote FTP server.

You can use the Folders section to create folders and folder shortcuts, download and upload files, and create a new SAS program. From the folders tree, you can expand and collapse folders and open items in folders by double-clicking them or dragging them to the work area.

Note: Files and folders that are located on an FTP server and are accessible by using an FTP shortcut cannot contain any of the following characters in their names:

{ } [ ] , : ; “ ‘ / \ | + < > ? @ # $ % ^ & ( ) + !

SAS Studio cannot access, move, rename, or delete files and folders on an FTP server whose names contain invalid characters.

To create a new folder shortcut:

Click Folders in the navigation pane. Then click and select Folder Shortcut. The New Folder Shortcut window opens.
In the Name box, enter the name of the folder.
From the Folder Type drop-down list, specify whether the shortcut refers to a SAS server folder or an FTP folder.
If you are creating a shortcut to a SAS server folder, enter the physical path for the directory in the Directory box.

If you are creating a shortcut to an FTP folder, enter the network address of the FTP host in the Host Name box as well as your user name and password. By default, the directory is the home directory of the FTP user. You can use the Directory box to specify another directory that is relative to the home directory. For example, if the home directory of the FTP user is c:\homedir, and you specify data in the Directory box, then the root directory of the shortcut is c:\homedir\data on the FTP server. You can validate your connection to the FTP server by clicking Test.

Note: If your mid-tier and FTP servers are running different operating systems, you must fully qualify the name of the FTP host in the Host Name box. If this name is not fully qualified, then the connection might fail.
Click Save to create the folder shortcut. The new shortcut is added to the list of folder shortcuts.

To create a new folder, select the folder in the Folders section in which you want to create the new folder. Click New button

and select Folder. The New Folder window opens. Enter the name of the new folder. The new folder is added to the list of folders.

To download a file, select the file that you want to download and click Download button

. You are prompted to open the file in the default application or save it to your local computer.

To upload one or more files from your local computer, select the folder to which you want to upload the files and click Upload button

. The Upload Files window opens. Click Choose Files to browse for the files that you want to upload.

Working with Tasks

The Tasks section of the navigation pane enables you to access tasks in SAS Studio. Tasks are based on SAS procedures and generate SAS code and formatted results for you. SAS Studio is shipped with several predefined tasks that you can run. You can also edit a copy of these predefined tasks, and you can create your own new tasks.

To create a new task, click New task button

. SAS Studio creates a template in the work area that you can use to create custom tasks for your site. Custom tasks can be accessed from the My Tasks folder. For more information, see Understanding Tasks in SAS Studio.

To edit a task that you have created, select the task from the My Tasks folder and click Edit button

. The XML code that is used to create the task is opened in the work area. If you want to edit a predefined task, you must first right-click the task and select Add to My Tasks. For more information, see Edit a Predefined Task.

Note: You can edit only the tasks that are in the My Tasks folder.

Working with Snippets

The Snippets section of the navigation pane enables you to access your code snippets. Code snippets are samples of commonly used SAS code that you can insert into your SAS program. SAS Studio is shipped with several predefined code snippets that you can use. You can also edit a copy of these snippets and create your own custom snippets. Your custom snippets can be accessed from the My Snippets folder. For more information, see Working with Programs.

To edit a snippet that you have created, select the snippet from the My Snippets folder and click Edit button

. If you want to edit a predefined snippet, you must first right-click the snippet and select Add to My Snippets.

Note: You can edit only the snippets that are in the My Snippets folder.

Working with Libraries

The Libraries section of the navigation pane enables you to access your SAS libraries. SAS tables are stored in SAS libraries. From the Libraries section, you can open SAS tables and add them to your programs. You can use the Libraries section to expand a table and view the columns in that table. The icon in front of the column name indicates the type.

Here are examples of common icons for the column types.

Icon	Type of Column
	Character
	Numeric
	Date
	Datetime

You can drag tables and columns from the Libraries section to a program, and SAS Studio adds code for the dragged items to your program. For more information, see Opening and Creating Programs.

You can also create new libraries and assign existing libraries.

To create a new library:

Click Libraries in the navigation pane and then click . The New Library window appears.
In the Name box, enter the libref for the library. The libref must be eight characters or fewer.
In the Path box, enter the physical path where the library resides.
In the Options box, specify any configuration options that you need. For the appropriate options, see the documentation for your operating environment.
If you want to access this library each time you use SAS Studio, select Re-create this library at start-up.
Click OK to create the library. The new library is added to the list of libraries in the navigation pane.

To assign unassigned libraries, click Assign libraries button

. If you want to access the selected libraries each time you use SAS Studio, select Assign selected libraries at start-up. If a library is unassigned, then you cannot access the tables in that library.

Using File Shortcuts

File shortcuts enable you to quickly access files that you specify. You can create a file shortcut to a file on your SAS server, via a URL, or on your FTP server.

Note: You can create a file shortcut to a file on an FTP server only if you have created a folder shortcut to an FTP folder.

To create a new file shortcut, click New file shortcut button

. You can define the shortcut by specifying a complete path and filename or by specifying a URL. If you want this shortcut to be available the next time you use SAS Studio, select Re-create this file shortcut at start-up.

You can open a file from a file shortcut by double-clicking it or dragging it to the work area.

The Choose Text Encoding window opens and you can select the encoding. This option applies to SAS program files (.SAS), text files (.txt), comma-separated values files, (.csv), and log (.log) file types.

Understanding Perspectives

Because SAS Studio can be used by a variety of people and groups within an organization, you can choose to view a specific subset of features, or perspective, that meets your needs best. Perspectives are sets of functionality that are customized to meet the needs of different types of users. SAS Studio includes two perspectives: the SAS Programmer perspective and the Visual Programmer perspective.

The SAS Programmer perspective is for users who intend to use SAS Studio mainly for writing and editing SAS programs. By default, the SAS Programmer perspective opens with a new program window and includes all five sections of the navigation pane so that you can easily manage all of your program files and code snippets.

The Visual Programmer perspective is designed for users who want to work with process flows in a project-based environment. You can use process flows in the Visual Programmer perspective to combine individual processes into one repeatable process flow that you can save, reuse, and share with other users. By default, the Visual Programmer perspective opens with a new process flow window and includes four sections in the navigation pane: Folders, Tasks, Snippets, and Libraries.

Note: If you open a process flow while you are using the SAS Programmer perspective, you are prompted to switch to the Visual Programmer perspective.

In both perspectives, you can run the predefined tasks that are shipped with SAS Studio, and you can create and edit tasks. You can also use both perspectives to create and run SAS programs and queries.

The differences between the perspectives can be viewed in the following table:

Element in SAS Studio	Available in SAS Programmer?	Available in Visual Programmer?
Navigation Pane sections
Folders	Yes	Yes
Tasks	Yes	Yes
Snippets	Yes	Yes
Libraries	Yes	Yes
File Shortcuts	Yes	Yes, but not displayed by default
SAS Programs	Yes	Yes
Queries	Yes	Yes
Process Flows	No	Yes

After you have started SAS Studio and selected a perspective, you can change the perspective that you are using by clicking the perspectives menu on the toolbar and selecting the perspective that you want to use.

You can specify which sections of the navigation pane are displayed in SAS Studio by clicking More application options button

and selecting View.

Editing the Autoexec File

The autoexec.sas file includes SAS statements that run each time you start SAS Studio and connect to your SAS server. For example, you can use the autoexec.sas file to assign libraries that you want to be available every time you use SAS Studio in both interactive and noninteractive modes.

Note: If you create a new library by using the New Library window, you can select the Re-create this library at start-up option to automatically add the LIBNAME statement to the autoexec.sas file. For more information, see Working with Libraries.

To edit the autoexec.sas file:

Click and select Edit Autoexec File.
Enter the code that you want to include in the autoexec.sas file.
To validate your syntax, click Run. The Log tab opens so that you can view the log.
Click Save to save and close the autoexec file.

Changing Your SAS Workspace Server

If you have access to more than one SAS workspace server, you can change the server that SAS Studio connects to. To change the server, click More application options button

and select Change SAS Workspace Server. Select the server that you want to use. When you change servers, any libraries and file shortcuts that you created are deleted. For more information, see SAS Studio: Administrator's Guide.
