SAS programming lecture 6:

Examples of Do Loops:

• Use of BY to control the counter
• Use of BY - (count)
• Use of a list of integers
• Do Until
• Do While
• Simple nested Do loops
• Nested Do loops with dependent indices
• Nested Do loops with a list
• Do loop with a character-valued list
• Do loop with a character-valued list and some new character functions

The other example program illustrates using Do loops for reading data, pointer control, and some other features.
