Hi Lee,

Replying to a message of Lee Aroner to Rachel Veraa:

 RV>> First, OS/2 doesn't use interrupts.  You have to use API calls. 
 RV>> Second,

 LA>    Not to niggle the point, but of course OS/2 uses interrupts. Each

No, Rachel is correct.

The OS/2 API is built on call gates and ring gates, not interrupts.
