Re: Database I/O Modernization

Is this type of interface familiar to you?

Yes.

What are the pros and cons of replacing existing I/O op codes with such
procedure calls?

Pro: Can't discern an advantage to this particular type of implementation.

Con: Non-standard unit-record I/O with more compile-time overhead and
more run-time overhead is no way to modernise.

Is this as an effective form of application modernization?

Adding Yet Another Dependent Layer is regressive.

Would you recommend a different type of interface?

Embedded SQL.

'Modern' for midrangers isn't about a particular I/O syntax. It's about
decoupling the logic from the database.
