You can use a custom ABLDoc Ant task to generate ABLDoc documentation for ABL sources. The ABLDoc Ant task is part of ant-abldoc.jar and is located at:
%DLC%\java
To generate ABLDoc using the ABLDoc Ant task, ensure that Apache Ant is installed on your machine and then copy the ant-abldoc.jar file to the installation location of Apache Ant.
These JAR files are available at: %DLC%\oeide\eclipse\plugins\com.progress.openedge.pdt.abldoc.core._version\lib (where version must specify the version number; for example: 11.5.0.00).
These artifacts are available at: %DLC%\oeide\eclipse\plugins\com.progress.openedge.pdt.abldoc.core._version\abldoc-artifacts (where version must specify the version number; for example: 11.5.0.00).
