Re: [sc-users] dynamic variable values

[tom tlalim <ttlalim@xxxxxxxxx>]

hi jeremy.
what are you trying to do?
if you are trying to access variables with an index,
is there a reason not to use an array for that?

(
var vview = [20, 21, 22];
vview[0].postln;
vview[1].postln;
vview[2].postln;
)


for the code you posted below to work you will need to declare the  
variable within the interpreted string

this works
(

	("var vview_0 = 20;
	vview_"++0).asString.interpret.postln;
)

if you do have a need for names rather than array slots, you can try  
to work with Environment or IdentityDictionary:

(
var d;
d = Environment.new;
d.put(\vview_0, 20);
d.put(\vview_1, 21);
d.use{"~vview_" ++ 1.asString.interpret.postln}
)

cheers,
tom
