Execute with CaptureOutput set to true doesn't returns rc

Execute() should return the rc of the program which gets executed if CaptureOutput is set to true, but it doesn't work here on MorphOS.
It always returns 0.
Did I something wrong?
Here is an example with tries to execute an unknown command "Echo2".
Code: Select all
@VERSION 11,0
rc, out = Execute("Echo2", "Hallo", {CaptureOutput=True})
DebugPrint("rc = "..rc)
DebugPrint("out = "..out)
If rc = 0
DebugPrint("Successful")
Else
DebugPrint("Failed!")
Endif

try the following example i test it in mos now works
comment/uncomment the two
Run()
Code: Select all
Function p_HandlerFunc(msg)
Switch(msg.action)
Case "RunFinished":
NPrint("Return code "..StrStr(msg.returncode))
NPrint("Press Return to continue.")
WaitLeftMouse()
EndSwitch
EndFunction
InstallEventHandler({RunFinished = p_HandlerFunc})
;Run("ed","",{Returncode=True}) ; returncode 0
Run("sss","",{Returncode=True}) ; dont exist not return code in win / returncode 10 in amigaos
Repeat
WaitEvent
Forever

I wanted to use Execute (), because it didn't have to run asynchronously.
And it should work according to the docs.

Your code is correct. But I'm not sure if it's a bug or a feature. I mean you're trying to execute a non-existing program here and technically non-existing programs can't return a return code so one could also say that it's correct for
Execute() to behave that way. I need to check how this behaves on other platforms and then decide about some sensible behaviour here...

based on discusion we had in
https://forums.hollywood-mal.com/viewtopic.php?t=4225 returncode must be what OS does
the following example works
in amigaos3.x by returning code 10 (As the OS does),
works in windows by returning 127 (as the OS does)
but not in Morphos/AmigaOS4
In morphos i see thext "failed code 10" in output text (as the OS does print in shell by executing a command)..bug or "feature"?
in AmigaOS4, works with 68kbinary, with ppc binary i see "return code 10" , if ed started without argument (missing) and "return code 0" if fail
Code: Select all
rc, output =Execute("ed","d",{CaptureOutput=True,Consolemode=True}) ; dont exist not return code in win / returncode 10 in amigaos
;rc, output =Execute("not_ed","",{CaptureOutput=True}) ; dont exist not return code in win / returncode 10 in amigaos
NPrint("Return code "..StrStr(rc))
NPrint("output "..output)
Repeat
WaitEvent
Forever

It also doesn't returns a returncode if the program exists.
Code: Select all
@VERSION 11,0
rc, out = Execute("c:RequesteChoice", "Hallo", {CaptureOutput=True})
DebugPrint("rc = "..rc)
DebugPrint("out = "..out)
If rc = 0
DebugPrint("Successful")
Else
DebugPrint("Failed!")
Endif

Huh? C:RequesteChoice doesn't exist or is that a typo?

It exists, but I only use one argument and miss the second necessary argument, to get sure that it returns a returncode (20).
Because you said that
Execute() only doesn't return a returncode, if the command doesn't exists.
