KSCAN(argument,n<,
delimiters>)
|
-
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 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. |
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.
