Syntax

CALL MISSING(varname1<, varname2, ...>);

Arguments

varname: specifies the name of SAS character or numeric variables.

Details

The CALL MISSING routine assigns an ordinary numeric missing value (.) to each numeric variable in the argument list.

The CALL MISSING routine assigns a character missing value (a blank) to each character variable in the argument list. If the current length of the character variable equals the maximum length, the current length is not changed. Otherwise, the current length is set to 1.

You can mix character and numeric variables in the argument list.

Comparison

The MISSING function checks whether the argument has a missing value but does not change the value of the argument.
