**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,
