Not Yet Supported ABL Features

As a general rule, far more is implemented already than is not implemented. For details on what is implemented already, please see Supported ABL Features.

If your application relies upon something in this (currently) unsupported list, please see this.

Most features in FWD v3.0.0 are from OpenEdge 10.2B or earlier. Generally, features added to OpenEdge after 10.2B are not yet supported. This document is a summary of the ABL features needing work.

The parser is more complete than the rest of the downstream conversion and the runtime. Although there may be some v11 features/keywords missing, nearly everything will parse today. This allows you to run reports and do a gap analysis on the results.


Very little is missing from the FWD preprocessor. See Preprocessor Unsupported Features for the details.


There are some obscure items that are still open. You can look in com/goldencode/p2j/uast/progress.g and search on the word TODO.
