KUPDATE(argument,position,n<,
characters-to-replace>)
|
|
KUPDATE(argument,position<,n>,
characters-to-replace)
|
-
argument
-
specifies a character variable.
-
position
-
specifies a numeric expression that is the
beginning character position.
-
n
-
specifies a numeric expression that is the
length of the substring to be replaced.
| Restriction: |
n cannot be larger than the length of the expression that remains
in argument after position. |
| Restriction: |
n is optional, but you cannot omit both n
and characters-to-replace from the function. |
| Tip: |
If you omit n, SAS uses all of the characters in characters-to-replace to replace the values
of argument. |
-
characters-to-replace
-
specifies a character expression that replaces
the contents of argument.
| Restriction: |
characters-to-replace is optional, but you cannot omit both characters-to-replace
and n from the function. |
| Tip: |
Enclose a literal string
of characters in quotation marks. |
The KUPDATE function replaces the value
of argument with the expression in characters-to-replace. KUPDATE replaces n
characters starting at the character you specify in position.
Note: If you set the NLSCOMPATMODE system option to
on, parameter, characters-to-replace, processes the
data based on previous SAS releases. If NLSCOMPATMODE is off, then characters-to-replace uses the 9.2 functionality. See the following
table for examples. ![[cautionend]](../../../../common/63294/HTML/default/images/cautend.gif)
