specifies a character
variable that is expressed as a scalar or as an array reference.
Restriction:You cannot use an expression as an argument.
Details
The VTRANSCODE function
returns 0 if transcoding is off, and 1 if transcoding is on.
By default, all character
variables in the DATA step are transcoded. You can use the TRANSCODE=
attribute of the ATTRIB statement to turn transcoding off.
Comparisons
The VTRANSCODE function returns
a value that indicates whether transcoding is enabled for the specified
variable. The VTRANSCODEX function, however, evaluates the argument
to determine the variable name. The function then returns the transcoding
status (on or off) that is associated with that variable name.
The VTRANSCODE function does not
accept an expression as an argument. The VTRANSCODEX function accepts
expressions, but the value of the specified expression cannot denote
an array reference.
Related functions return the value
of other variable attributes, such as the variable name, type, format,
and length. For a list of the variable attributes, see the “Variable
Information” functions in SAS Functions and CALL Routines: Reference.
