Hi Fausto, everything is fine, except that you need to manually modify the functions that were mentioned in the warnings. What happened is this: GNU APL reads an .atf file. The .atf file contains APL code that (tries to) reconstructs the variables and functions of the workspace that was written into the .atf file. The APL code that constructs functions usually has the form: ⎕FX 'fun-header' 'fun-line-1' 'fun-line-2' ... Now it is possible that the ⎕FX fails. In the .atf file that we are talking about there were two types of failures: 3 illegal tokens in function ∆xfrfrom and an illegal character in function ∆Oins. Illegal characters are detected by the APL tokenizer while illegal tokens have passed the tokenizer but were detected by the APL parser. Both failures generate a SYNTAX ERROR warning, but only when reading an .atf file. The bad character in your .atf file was ⎕AV[⎕IO + 161] or Unicode U+00BD. It looks a bit like '1/2' but has no APL2 significance (though it may have significance in other interpreters). When GNU APL reads an .atf file with errors like the above then it prefixes the offending line(s) with ## and prints the warning mentioning the function name containing the line. You are then supposed to fix the errors manually (removing the ## and replacing the rest by some correct code. If you display such a function (which actually opens, displays, and closes it) then you get a DEFN ERROR+ (where the + tells you that command )MORE has more info about the error. In your case the not-removed ## in line [3] of function ∆Oins was raising the DEFN ERROR. /// Jürgen On 04/27/2015 07:53 AM, Fausto Saporito
