Subject: RE : save attributes in ascii file

Dear Paul,
Clearly the settings of your VisualWorks image are incorrect.
Getting decompiled code make it very difficult to understand how a method
works…
Not only have you lost the names of the variables, but also the explanatory
comments:
"Save the attributes of the intances of aClass on a file 'aStringOrFilename'
attributes <OrderedCollection> ex: OrderedCollection ('seed' 'context')
file <Filename> ex: aFATFilename('d:\vw7nc\cormas\Models\TSE\data\titi.txt')
or
file <String> ex: 'titi.txt' it will be save into data/"
Thus to enter the first argument as a literal value, if you just want to
export one attribute named #xx, you should use
#(’xx’)
As for the last argument, you should use
$;
and not
Cormas separator
HTH,

Objet : save attributes in ascii file
Hi All,
I am trying to make my model save some of the grid's attributes during the
simulation.
I use the following method:
saveAttributes:#xx
fromClass: Class
inFile: 'file.txt'
separator: Cormas separator
I have also tried to put "$;" as "separator:" argument.
My Class is never nil, the attribute #xx neither, it ranges from 0 to 200.
Then I get a "Unhandled exception: Message not understood: #n" that arises
in an "optimized block" in the "CormasModel>>getAttributesType: t1
fromInstances: t2", in the line
"t3:=t2 detect:[: t8 | t8 perform: t7 asSymbol) isNil not]"
As the whole is decompiled code I am not very sure I have understood how it
works, but the ".t7" value is weird: $n "16r006E", and probably the "message
not understood:#n" refers to the n after the $ ???
thank you for your help
Paul
