This is a bug in my brain but related to GNU APL. Last time I used APL was when I worked at IPSA. The language has been extended since then.
I have the ISO Standard and even the IBM APL2 Language Summary & Programming Guide. What can I read for a summary of the differences between the APL I know/knew and GNU APL - ISO 13751? (In my days at IPSA I shared an office with one of the authors of the ISO std) TIA & respect Peter
