thanks very much for the response to
my queries. i think the problem with trying to )IN my .atf files
may have been how the apl characters were encoded using ascii codepoints
by ibm apl2 and this may have resulted in some confusion, since in some
cases i may have tried to edit a .atf file and introduced some utf8-encodings.
i'll write an apl function to edit binary versions of the .atf files
to at least replace all the ascii with utf8, and see what happens. i'll
let you know.
i also finally seem to have the union
keyboard that i'd been using forever with apl2 working properly for gnu-apl
on my mac
best regards

Re: [Bug-apl]
trying to run gnu-apl on a Mac
Hi Jeff,
regarding )IN if I remember correctly then (relative) file names of .atf
files are from some root directory as shown by )LIBS. If that does not work then try absolute file names (i.e.
starting with / ).
The .atf files read by )IN are not supposed to be utf-8 encoded. )IN also
does some translation from the IBM code pages to the proper unicode characters, I was able to
read some IBM APL2 files that were shipped with the APL2 evaluation package, e.g. workspace
DISPLAY.
On the other hand ⎕FIO[49] probably assumes an utf-8 encoded text file.
For reading bytes, ⎕FIO[41] may be a better choice.
I would assume that using )IN is much simpler than using ⎕FIO[49] and
if that fails then I would like to know about and fix it.
If you need more help, please don't hesitate to ask.
Best Regards, Jürgen Sauermann

i'm trying to get gnu-apl running on a Mac under macOS Mojave 10.14.4,
i installed it using brew. i have a large number of .atf files
that were generated using ibm apl2 under windows. when i try to )in
one of them i get 'no such file or directory'. if i try to read a
transfeer file with ⎕FIO[49] i get an (almost) endless stream of 'truncated
UTF8 string' errors. is there an assumption that a .atf file is UTF8-encoded?
is there some other problem
any help would be greatly appreciated. thanks in advance
