Subject:      missing value function ?
Content-Type: text

I am having troubles using one of the missing value functions on the
release 4.0 of SPSS running on a unix mainframe.  According to the SPSS
reference guide, the following command should return the number of
missing values for each case on the listed variables:
 
compute newvar = missing(x1) + missing(x2) + missing(x3)
 
So I should be getting a value ranging from 0 to 3 for each case.
Instead, I keep getting an error message stating the following:
 
Error 4307.  Text: + . One of the operands for the arithmetic operation
is other than a numeric variable or numeric expression.
 
Any clues?  Does this function no longer work?  BTW, all of the vars are
numeric variables.
 
Thanks,
