Re: Latin-American APL keyboard layout?

Hi APLer, let me propose another approach - don't fiddle with keyboard layouts anymore to get APL-symbols. I think this is a bite reflex from the past - APL symbols → I need a specific keyboard layout. Most operating systems offer compose keys, and they are much easier to configure, and independ

canceling ∇-edit mode

Hi APLers, first let me thank, for that wonderful piece of software! Using the ∇-editor I found some inconsistencies, perhaps a bug or am I using ∇ wrong? Reference APL2 docu and Nabla.cc: " // we expect one of the following: // // [⎕] [n⎕] [⎕m] [n⎕m] [⎕n-m](show) //

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
