isCOBOL IDE embeds isCOBOL compiler and runtime libraries of the same version and bitness. It’s possible to link external isCOBOL SDKs in order to compile and run your programs with a different version of isCOBOL.

Click on the Add button and browse for the desired isCOBOL SDK main folder. The selected folder must include "bin" and "lib" subfolders where isCOBOL compiler and runtime libraries are found.

If the selected folder is recognized as a valid isCOBOL SDK, a new line appears in the table and you can now choose which isCOBOL SDK must be used. The choice made here is applied to every new project created in the workspace.

Note - The isCOBOL SDK version must be 2017 R1 or greater. It’s not possible to link older isCOBOL SDKs.
