The API samples in the directories rexxapi1, rexxapi2, rexxapi3 demonstrate how to:
|
|
|
|
- Register external functions from within external functions
|
|
- How you can provide external functions (written in C) in a library that can
|
|
be accessed from Open Object Rexx (after they have been registered)
|
|
- How data can be returned from external functions
|
|
- How the REXX Variable Pool Interface can be used to access and modify Open
|
|
Object Rexx variables
|
