Today I was able to create (untested) Windows versions (32/64bit, with and without debug infos) of ooRexx from the current trunk. Here is the Dropbox-link: <https://www.dropbox.com/sh/lsu8inlo2o99j96/AABHGsFLe9E0OVwjehRINwdZa?dl=0>.
The trunk version does not include address with or variable references. For that Windows 64-bit debug versions can be fetched from my Dropbox from: <https://www.dropbox.com/sh/olh1mqfwb4brp7r/AABI1X-Le9zDCJ0gyfvMdKB8a?dl=0>. All of these ooRexx installation packages will be available at least over the weekend. ---rony On 11.07.2018 17:18, Rony G.
