Syntax

<variable=>SUBSTR(argument,position<,n>)

Arguments

variable

specifies a valid SAS variable name.

argument

specifies any SAS character expression.

position

specifies a numeric expression that is the beginning character position.

n

specifies a numeric expression that is the length of the substring to extract.

Interaction:	If n is larger than the length of the expression that remains in *argument* after *position*, SAS extracts the remainder of the expression.
Tip:	If you omit n, SAS extracts the remainder of the expression.

Details

The SUBSTR function returns a portion of an expression that you specify in argument. The portion begins with the character specified by position and is the number of characters specified by n.

A variable that is created by SUBSTR obtains its length from the length of argument.
