Managing Custom Code – Best Practices

• Custom code mostly similar to R17

• A few subtle (but important) differences:

• • Oracle, SQL, Unidata distributed code MUST
  • • Be in toolkit
    • Not perform direct Unibasic file I/O (READ/WRITE)
    • Not perform direct MIO calls
  • Unidata combined does not have these limitations
  • • But STRONGLY RECOMMENDED
    • Non-compliant code may not work in future releases
    • If time to implement is short, focus on computed columns first
