Syntax

SUBPAD(string, position <, length>)

Arguments

string

specifies a character constant, variable, or expression.

position

is a positive integer that specifies the position of the first character in the substring.

length

is a non-negative integer that specifies the length of the substring. If you do not specify length, the SUBPAD function returns the substring that extends from the position that you specify to the end of the string.


Details

In a DATA step, if the SUBPAD function returns a value to a variable that has not previously been assigned a length, then that variable is given a length of 200 bytes.

If the substring that you specify extends beyond the length of the string, the result is padded with blanks.


Comparisons

The SUBPAD function is similar to the SUBSTR function except for the following differences:
