Syntax

KSCAN(argument,n<, delimiters>)

Arguments

argument

specifies any character expression.

n

specifies a numeric expression that produces the number of the word in the character string you want KSCAN to select.

Tip:

If n is negative, KSCAN selects the word in the character string starting from the end of the string. If |n| is greater than the number of words in the character string, KSCAN returns a blank value.

delimiters

specifies a character expression that produces characters that you want KSCAN to use as word separators in the character string.

Default:

If you omit delimiters in an ASCII environment, SAS uses the following characters:

blank . < ( + & ! $ * ) ; ^ - / , % |

In ASCII environments without the ^ character, KSCAN uses the ~ character instead.

If you omit delimiters on an EBCDIC environment, SAS uses the following characters:

blank . < ( + | & ! $ * ) ; ¬ - / , % | ¢

Tip:

If you represent delimiters as a constant, enclose delimiters in quotation marks.

Details

Leading delimiters before the first word in the character string do not effect KSCAN. If there are two or more contiguous delimiters, KSCAN treats them as one.
