Hello,
As a workaround, if you replace
1!=0 // syntax error
with
str="1!=0";
evstr(str);
it seems to work as you expected.
Anyway, I think the try/catch structure can catch errors occurring at
runtime (like division by zero, etc ...), but not syntax errors.
You are supposed to write syntactically correct Scilab!

Hi,
In scilab-5 I used to save console output of script file execution in a
text file with "diary", this seems to fail in scilab-6, for new errors
types recently added (Syntax error, Unexpected token ). Perhaps I
misunderstood something in try/catch statement , let's consider the file
bug_syntax_error.sce containing :
diary(0)
diary('file.txt','new');
try disp('let''s make an error')
1!=0 // syntax error
catch
disp('added to diary')
end
diary('file.txt','close')
execute this script with CTRL+SHIFT+E or "exec" will not create file.txt
--> exec('bug_syntax_error.sce', -1)
à la ligne 4 du fichier exécuté bug_syntax_error.sce
1!=0 // syntax error
^^
Erreur : Unexpected token '!'
--> mgetl file.txt
mgetl : Impossible d'ouvrir le fichier file.txt.
execute this script from scinotes with CTRL+E will give :
--> diary(0)
--> diary('file.txt','new');
--> try disp('let''s make an error')
> 1!=0 // syntax error
> catch
> disp('added to diary')
> end
1!=0 // syntax error
^^
Erreur : Unexpected token '!'
--> diary('file.txt','close')
--> mgetl file.txt
ans =

!Erreur : Unexpected token '!' !

!--> diary('file.txt','close') !
I also remark that those new errors (like bad comparisons 1=2 or bad
string delimiters mixing ' and " ) have no localization. This doesn't
happend with "old" errors (which have localization), replacing "1!=0"
with "ieee(0),1/0" I get :
--> exec('bug_syntax_error.sce', -1)
let's make an error
added to diary
--> mgetl file.txt
ans =
! !
! !
! let's make an error !
! !
! !
! !
! added to diary !
Best regards,
Philippe
