SAVE Subcommand (TWOSTEP CLUSTER command)
The SAVE subcommand allows you to save cluster
output to the active dataset.
CLUSTER. Save the cluster identification. The cluster
number for each case is saved. You can specify a variable name using
the VARIABLE keyword, otherwise, it is saved to TSC_n,
where n is a positive integer indicating the ordinal of the SAVE operation
completed by this procedure in a given session. If you specify a variable
name with the VARIABLE keyword, it cannot be a variable
that already exists; it must be a new, unique variable name.
