Syntax

KSUBSTRB(argument,position<,n> )

Required Arguments

argument
specifies any SAS character expression.
position
specifies the beginning character position in byte units.
n
specifies the length of the substring to extract in byte units.
Interaction:If n is larger than the length (in byte units) 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

See Internationalization Compatibility for SAS String Functions for restrictions and more information.
The KSUBSTRB function returns a portion of an expression that you specify in argument. The portion begins with the byte unit specified by position and is the number of byte units specified by n.
A variable that is created by KSUBSTRB obtains its length from the length of argument.
