APPC Verbs

This chapter documents the syntax of each verb passed across the APPC API, and describes the parameters passed in and returned for each verb.

This chapter also provides reference information for the APPC basic and mapped conversation verbs that are provided for APPC duplex and half-duplex conversations. As you read through this chapter, you will discover that the basic and mapped verbs are very similar and that is why they have been combined into one chapter. However, there are some differences. Those differences are denoted as follows:
