[EpiData-list] Multiple Diagnosis

Dear Epidata Team,                   We have a patient's database. A patient can have multiplediagnosis. Hence these are the numerically coded variables defined for dataentry of ;Diag, Diag2, Diag3, Diag4, Diag5, Diag6. Of course one can FREQ theIndividual "diag" and see the individual diagnosis pattern. However if onewants to see the pattern of common diagnostic combinations observed inall the patients, is there any way out?  Dr. Shavinder Singh
