Hello Jurgen,
Yes, e.g.
E.g. the classical 2>&1 e.g.g:\cygwin32\bin\apl.exe --noSV -s -f
c:/temp/helloworld.apl c:/temp/ddd.txt 2>&1
E.g. 2>
> g:\cygwin32\bin\apl.exe --noSV -s -f c:/temp/helloworld.apl 2> c:/temp/ddd.txt
Note: I have installed 10s of other programming languages lately, there e.g.
2>&1 basically always works to get the error output.But in apl.exe it never
worked, whatever tried.
Thanks

APL versions would use stderr (and not stdout) for all output, but I can't
quite remember
when (and if) that was changed. The apl.exe files are usually somewhat older
than those
in SVN, so maybe they suffer from that.

Hello Jurgen,
I assume that this is only reproducible in Microsoft Windows.
If I try it with MSDOS cmd.exe and trying /cygdrive/c/temp/ it shows that it
can not find that path.

Hi Knud,
I tried this, both on GNU/Linux and on cygwin in a VM running Windows XP
(since I do not have a
native Windows machine) and running apl in a cygwin shell:
apl --LX '"Hello World" > /tmp/x
In both cases /tmp/x was created and contained the GNU APL startup banner and
the "Hello World".
In my experience the Windows C: drive notation is not understood in all cygwin
contexts,
maybe you should try /cygdrive/c instead of C: ?
Best Regards,
Jürgen

Hello Jurgen,
So looking again into this.
It is definitely a bug of apl on Microsoft Windows is my current opinion.
No output to a file is or can be generated.
Tried e.g.
g:\cygwin32\bin\apl.exe --noSV -f c:/temp/helloworld.apl >c:/temp/ddd.txt
g:\cygwin32\bin\apl.exe --noSV -s -f c:/temp/helloworld.apl >c:/temp/ddd.txt
2>&1
g:\cygwin32\bin\apl.exe --noSV -s -f c:/temp/helloworld.apl 2> c:/temp/ddd.txt
g:\cygwin32\bin\apl.exe --noSV -f c:/temp/helloworld.apl >c:/temp/ddd.txt 2>&1
...
Usually Cygwin programs running on Windows have the same behavior as on
Linux, so this is unexpected.
I am mainly interested in capturing the STDERR thus in order to debug errors.
This is e.g. the program used (helloworld.apl)
'Hello world' df -df ---- )OFF
so the error thrown is
Hello world VALUE ERROR df-df---- ^
It is thus impossible to catch this error in a file.

As a next step: Is there maybe somewhere a latest pre-compiled binary
executable version of Cygwin GNU APL.exe available somewhere?

Hi Knud,
GNU APL prints to stdout and stderr like all other "normal" programs.
It might be, though, that under non-normal operating such as WINDOWS
the output gets lost for some reason.
I suppose that the shell used (e.g. cmd.exe vs. the cygwin shell) might
make a difference in that respect. The following works just fine in GNU/Linux:
eedjsa@server68:~/apl-1.8$
eedjsa@server68:~/apl-1.8$
eedjsa@server68:~/apl-1.8$
eedjsa@server68:~/apl-1.8$ cat test.apl # prints ⍳10
⍳10
)OFF
eedjsa@server68:~/apl-1.8$ apl -s -f ./test.apl > test.output
eedjsa@server68:~/apl-1.8$ cat test.output
1 2 3 4 5 6 7 8 9 10
eedjsa@server68:~/apl-1.8$
eedjsa@server68:~/apl-1.8$

Hello,
1. apl.exe has a parameter to input a file.
2. E.g.
apl.exe -f youraplfilenamehere
E.g.
apl.exe -f helloworld.apl
3. But how to get the output of it?
4. There seems to be no command line parameter to set output to a file (run
e.g. apl.exe --help to see and check that).
5. Also something like pipe '>' to a file gives no results.
E.g.
apl.exe -f helloworld.apl >youroutputfilename
Can you please advise?
Thanks with friendly greetings Knud van Eeden
