decompress -> result = 1

[Klaus Major]

Hi all,

can someone maybe give me a little hint what the result 1 means when I  
decompress a file?

Here is an excerpt of an update/install routine of our current project.
This is happening on a Mac, will have to test on windows later.

All filenames, references etc. are VALID!

...
## Dateinamen zusammenbasteln...
## CONTRUCT FILENAMES
   put the ims_installer_ordner of this stack & "win_exe.gz" into win_gz
   put win_ordner & "iDual IMS.exe" into win_ziel

   ## Dateien kopieren...
  ## COPY FILES
   ## EXE
   put url("binfile:" & win_gz) into w1
   put decompress(w1) into w2
   if the result <> empty then

############### Error decompressing Windows Runtime#########
     answer "Fehler beim entpacken der Windows Runtime!" & CR & the  
result
################ HERE I get "1" as the result***

     alles_auf_anfang
     exit to top
################ !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! see below...

   end if

### WORKS!???
   put w2 into url("binfile:" & win_ziel)
   if the result <> empty then

### WORKS!???
     answer "Fehler beim schreiben der Windows Runtime!" & CR & the  
result
     alles_auf_anfang
     exit to top
   end if
###
...

***
The REALLY strange things are: the other decompress actions run  
without errors
AND although there is an "exit to top" statement, the scripts keeps on  
running and
afterwards EVERYTHING has been installed without problems?

So does "1" as the result of a decompress action really indicate that  
something went wrong?
Could not find a hint in the docs.

Any insights very welcome.
Thanks in advance!


Best
