Syntax
KSCAN(argument,n<, delimiters> )
Required Arguments
- argument
-
specifies any character
expression.
- n
-
specifies a numeric
expression that produces the number of the word in the character expression
you want KSCAN to select.
Tip:If n is negative,
KSCAN selects the word in the character expression starting from the
end of the string. If |n| is
greater than the number of words in the character expression, KSCAN
returns a blank value.
- delimiters
-
specifies a character
variable that produces characters that you want KSCAN to use as word
separators in the character expression.
Default:If you omit
delimiters in an ASCII environment, SAS uses
blank . <
( + & ! $ * ) ; ^ – / , % |. In ASCII
environments without the ^ character, KSCAN uses the ~ character instead.
If you omit delimiters on an EBCDIC environment, SAS uses 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.
