Lecture 2

• Identify elements SAS System and Course SYNTEX
• Program to Read data, Print Data and Tabulate Results (lec1sm5.sas)
• What you need to Know about Windows
  • How to move from one window to another, use the mouse, shrink and enlarge windows, display multiple windows.
  • How to start and create a simple word processing document, change the fonts, and save the document on a floppy disk.
  • How to access the WEB, and move from one page to another on it using the mouse.
  • How to cut and paste information from one window to another window.

• DATA
  • INPUT
  • CARDS
• RUN
• Typing Data Into SAS
• Variable Names must
  • a. contain from 1 to 8 characters
  • b. must have as the 1st character a letter or the underscore ("_")
  • c. cannot contain blanks
  • d. If variables contain characters, then a "$" follows the variable name. The "$" specification stores the variables in a "character" format, as opposed to a numeric format. A simple example is given in LEC13P5.SAS.

• Adding a comment with your name and date
• Using the KEYS to move in the SAS Display Manager

• You can add buttons. An example is a button that will:
  • clear the log window
  • clear the output window
  • run the program in the program window
  • move to the log window
  • search from the top of the log to the first ERROR

Use a system to keep track of SAS Programs, re-using the same pieces of the system for each program. The system includes:

• Program name: lec10p1.sas, lec10p2.sas, etc
• Header for program including:
  • OPTIONS statement
  • TITLE1 statment with program name, date, storage location, programmer
  • Brief Description
  • Standard LIBNAMES
• Copy header in each time, changing program number and description- immediately use SAVE AS to rename saved SAS program.
