Split Files (CLUSTER command)

  • When split-file processing is in effect, the first variables in the matrix data file are the split variables, followed by ROWTYPE_, the case-identifier variable or ID, VARNAME_, and the distance variables.
  • A full set of matrix materials is written for each split-file group defined by the split variables.
  • A split variable cannot have the same name as any other variable written to the matrix data file.
  • If split-file processing is in effect when a matrix is written, the same split file must be in effect when that matrix is read by any procedure.
