Dear APLers, I don't think this is a bug, but intentionally:
Doing f.e.: { 3 } ¨ ⍳5 results in gnu-apl to an error: SYNTAX ERROR λ1¨⍳5 ^ ^ In other APLs, this works just fine, f.e. dyalog (or even april): { 3 } ¨ ⍳5 3 3 3 3 3 More general without Each/¨, f.e. { 3 } 55 results in gnu-apl in 3 55 but in dyalog (and others) in 3 What's the background of this different behavior in gnu-apl? I also couldn't find any hint in IBMs APL2 Reference for this behavior. br & and many thanks for any hint! br Otto
