How does Reverse API handle code page and client generation?

Reverse API is a Hub project with technology REVERSE: legacy COBOL/RPG calls a modern HTTP API through OLREVAPI. It is not “add an AS/400 RPC asset.”

Client generation

In OL Code: Generate From Hub (published REVERSE method) or Generate API Client from OpenAPI. Client types include z/OS CICS COBOL, z/OS COBOL, AS400_COBOL, and AS400_RPG.

Code page / EBCDIC and Unicode

Conversion uses the code page configured on the Reverse API / host runtime, not an implicit guess from the OpenAPI spec. If the option is missing in the UI, set it on the Reverse project or runtime (and in generated OLAPICPY / platform settings). BIDI / DBCS need explicit format support in the contract and the reverse runtime; they are not on by default.

Where is Reverse API for AS/400?

A REVERSE project with client type AS400_COBOL or AS400_RPG, then Generate From Hub into an IBM i dataset.
