<variable=>SUBSTR(string, position<,length>) Details In a DATA step, if the SUBSTR (right of =) function returns a value to a variable that has not previously been assigned a length, then that variable is given
The SAS(R) SUBSTR function differs from the substring function in other programming languages as it can be used on either side of the assignment operator. This paper demonstrates its practical usage by building programs to separate and manipulate text. Specific topics include: Proper Syntax Use; ...

If you have used repetitive INDEX and SUBSTR functions to determine how many times a “word” occurs in a character string, that task can also be accomplished more easily in Version 9. The COUNT function determines the number of times argument 2 occurs in argument 1. ...
The following SAS program filters data where the first two characters of the 'name' variable are 'DA' or 'da'. TheSUBSTRfunction is used to extract the first two characters of the name variable, and theUPCASEfunction converts them to uppercase so that we can select both 'DA' and 'da...
33 The SAS SUBSTR function can be used to restrict The same result can be achieved by changing the the number of characters that are included in a operator from an equal sign (=) to an equal sign compare. As in this example that compares 3, 4, followed by a colon (=:). This ...
