Add a new folder called projects
Double click it (to open it)

5. Setup Windows
The projects folder is inside of the c drive.
This path is abbreviated c:\Projects

14. Allowing EG to Talk to DOS
Using DOS
Allowing EG to Talk to DOS
There are times when you want to have SAS or EG ask Windows to do a task. For example, you may want to have a folder (directory) created automatically or you may want to set the folder where SAS should look for files or where results will be stored by default.
The easiest way to do this is to type programming commands in DOS (the file manipulation system that predates modern Microsoft Windows).
Another word for the operating system is the shell.

15. DOS Stuff There are only a few commands you want to bother with
Using DOS
DOS Stuff
There are only a few commands you want to bother with
mkdir = make a directory
mkdir c:\blah
del = delete something
del /Q c:\blah\*.*
cd = change to a directory
cd c:\blah

16. Shell Escape In SAS programs you can type DOS commands like this:
Using DOS
Shell Escape
In SAS programs you can type DOS commands like this:
X "dos stuff goes here";
These are called shell escapes. Obviously, shell escapes are dangerous tricks that give you the power to do all kinds of mischief including erasing a hard drive.
By default, Enterprise Guide does not allow them. You need to tweak the registry to turn the functionality back on.

17. Shell Escape Commands in EG
Using DOS
Shell Escape Commands in EG
Tweak to the registry:
1. Start => Run => enter REGEDIT => OK.
2. Select hkey_classes_root => clsid => {440196D => localserver32.
3. Right-mouse on Default and select Modify.
Be careful here.
4. Remove -noxcmd (should be the last item in the list) => Ok.
5. View => Refresh.
6. Exit the Registry window.
7. Reboot
Backup your registry before you change anything: support.microsoft.com/kb/322756
Ask for help if you have the slightest question.

19. Change the Default File Location
Configure SAS
Change the Default File Location
On every machine you use, you should change the default file location to the work library. Do this once per machine.

20. Configure SAS
Click 1st
Click 2x

21. Other Options To save your sanity, make this change to the options.

22. Custom Code for Graphics
Configure SAS
Analyses in SAS 9.2 can have extra high resolution graphics. Permanently turn them on.

23. Configure SAS
Making Code Easy
To make it easier to write code I have prepared keyboard macros that will let you fill in the blanks in code rather than having to memorize the details of the language.
Download the file
Open a code node, then from the Program menu, choose Editor Macros and click Macros.
Choose Import… and select the file you downloaded

24. Configure SAS

25. Configure SAS
Using the Macros
When you type the name of an analysis or data management procedure, a "tool tip" will appear. Push the Tab key to have SAS include the code I wrote.

26. Using SAS
Permanent Store
I suggest that you save your data into the temporary work library by default.
If you have a huge file which you only want to import once, or if you want to keep a permanent copy of a SAS data file, you will want to set up a permanent library.
This is just a fancy way of specifying what folder SAS should use to save the .sas7bdat data files.

27. Custom Icons
SAS 9.2 TS2 can not assign a library to a folder that has ever had a custom icon. It is OK to use the custom icon to mark a folder as an active project but you will need to add a folder inside of it with a normal icon to hold the data.

28. I suggest you use the c:\projects folder on your hard drive but if you do not have permission, you can use the desktop. To point EG to a library on your desktop you need to navigate to a path like: c:\Documents and Settings\blah\Desktop where blah is your account name on the PC.

29. Download the Data (1) Make the directory to hold the data… with DOS!!!
Click the windows start button
Click Run…
Type cmd and push enter
type mkdir c:\projects\hrp223\lab1 and push enter
I go here for DOS questions:

31. Importing the Easy Way
Using SAS Libraries
The most bulletproof way for importing with EG 4.2 is to use the import wizard.

33. C:\Documents and Settings\AccountName\Desktop
Using SAS Libraries
If you have problems with access to folders you can use the Desktop
C:\Documents and Settings\AccountName\Desktop

34. Using SAS Libraries
You must click on the folder you want to use as a library. Expanding the tree is not enough.
BAD
Good

35. Using SAS Libraries
2nd add a line to the flowchart connecting the library to the import. It just looks good.
1st rename the node to match the library name

38. Using SAS Data
Playing with Data
Once the data is imported, you can add code “nodes” to the flowchart or use the graphical user interface to tweak the data and do analyses.

Converting Characters to Numbers
If you want to convert a variable that is a character into numeric use the input function. Keep in mind that all values that include non-numeric values will be erased.

46. Using SAS for Toy Data
Toy Data Sets
It used to be that you needed to memorize lots of arcane syntax to accomplish even the easiest of tasks, like making a toy data set.
data humans;
input isDead $ age;
datalines;
true 20
false 45
false 21
true 67 ;
run;

They can’t do some complicated tasks.

48. Data Step vs. Proc SQL The EG data manipulation tools use SQL.
Using SAS for Toy Data
Data Step vs. Proc SQL
The EG data manipulation tools use SQL.
For simple tasks you can use either language (or point and click) but for complicated tasks, each has advantages which I will eventually show you.

SAS Data Step vs. SQL
SQL is a nearly universal language for accessing, querying and changing data in databases.
Most tasks can be easily done by having the SAS GUI write SQL for you.
Data step programming is the language used only by SAS.
Some frequently done tasks can be done quickly and easily with data step programming.
splitting tables into several new tables
processing groups of records

60. Using SAS for Real Data
Procedures
In addition to data step programming, the other major part of the SAS programming language is the use of procedures for analysis (and complex data manipulation).
You can memorize the syntax and write PROC code or you can use EG and have it do the work for you.
