The coding and filing of pathologic diagnoses have been heavy tasks; however with the availability of inexpensive microcomputer, a system may be developed that permits storage and retrieval to be performed efficiently. With Apple II(R) computer system and SNOP coding, a simple program using dBASE-II and QUICKCODE computer program can be created to include the following informations: accession number, chart number, sex and age of patients and 2 diagnosis codes. Once SNOP coding is carried out by medical staff, a secretary or clerk can enter the informations into the microcomputer. Data may be searched on any combination of the above parameters.
