When saving classmembership the output file contains only the usevariables, I would like to be able to export the class membership variable back into the original SPSS file for basic handling. How can I make the output contain the id-variable inorder to match the original file?

thanks in advance

See the IDVARIABLE option of the VARIABLE command.

Thank you Linda! Is there an option som the output has some digit instead of star sign. for missing in the output file?

Sorry for misspellings,it should read:

is there an option (in the synthax) so a digit/value (ex -999) replaces the star sign for the mssing values in the saved output?

When I use IDVARIABLE command as followed:

USEVARIABLES = rattkod aHAD_ang dHAD_ang EHAD_ang fHAD_ang;
IDVARIABLE = rattkod;

MISSING = ALL(-999);
CLASSES = c(4);
and "rattkod" being the variable with the id-kod in it, I get the following error message

Invalid symbol in data file:
"1101" at record #: 1, field #: 1

Inspecting the data in the text file, I see that 1101 is my first id-value (first person first variable).
Why is the programm not being able to read it and what is ""?

See the MISSFLAG option of the SAVEDATA command.
