• Target variables are always numeric and are initialized to 0 for each case. They are assigned
a dictionary format of F8.2.
• If the target variable already exists, its previous values are replaced.
• COUNT ignores the missing-value status of user-missing values. It counts a value even if
that value has been previously declared as missing.
• The target variable is never system-missing. To define user-missing values for target variables,
use the RECODE or MISSING VALUES command.
• SYSMIS counts system-missing values for numeric variables.
• MISSING counts both user- and system-missing values for numeric variables.
COUNT TARGET=V1 V2 V3 (2).
• The value of TARGET for each case will be either 0, 1, 2, or 3, depending on the number
of times the value 2 occurs across the three variables for each case.
• TARGET is a numeric variable with an F8.2 format.
COUNT QLOW=Q1 TO Q10 (LO THRU 0)
/QSYSMIS=Q1 TO Q10 (SYSMIS).
• Assuming that there are 10 variables between and including Q1 and Q10 in the working
data file, QLOW ranges from 0 to 10, depending on the number of times a case has a negative
or 0 value across the variables Q1 to Q10.
• QSYSMIS ranges from 0 to 10, depending on how many system-missing values are encountered
for Q1 to Q10 for each case. User-missing values are not counted.
• Both QLOW and QSYSMIS are numeric variables and have F8.2 formats.
COUNT SVAR=V1 V2 (’male ’) V3 V4 V5 (’female’).
• SVAR ranges from 0 to 5, depending on the number of times a case has a value of male
for V1 and V2 and a value of female for V3, V4, and V5.
• SVAR is a numeric variable with an F8.2 format.
