Question:

What file types are supported?

Answer:

CA-XCOM for NonStop(Tandem) supports the following Format 1 and Format 2 file types through ENSCRIBE, Tandem's disk file architecture:

  • Structured

    • Relative

    • Entry Sequence

    • Key Sequence

  • Unstructured

    • Edit

Structured files are record oriented (much like VSAM on the mainframe) and Unstructured a large byte array (much like a stream file on UNIX).

CA-XCOM for Nonstop(Tandem) uses a number Guardian system functions to manage (open, write, close, and position) all file I/O.
