Hi,
Maybe this is not the right place to ask this question. Do not hesitate to tell me so if that’s the case. I am completely new to APL and I am looking for a learning resource (preferably a book, but other media would be fine) that would be compatible with GNU APL. I have found documentation for proprietary versions of APL that I prefer to stay away from and I understand that these have substantial differences wrt GNU APL. I have browsed the resources available at https://www.gnu.org/software/apl/Community.html, but I find them difficult for a beginner like me and I would need a more structured approach to learning APL. Do not hesitate to point me somewhere else if this is not the appropriate forum for my request. Thanks for your time and attention. G. Dindi
