Acess variables with "variable" names

[lemmans]

Hi everyone:

Here is my problem:

I generate variables of the type: a1 a2 a3...a"n"
I do it in a "for" loop

The problem is when I want to access to the values contained in this variables (again in another "for" loop):

I can't access to its values using $a$i (been "i" another varible that its changing in the loop) because it says that $a doesn't exists. Off course it doesn't exists , I want to access a1 a2...an

I've tried with $a($i) and similar things, but I don't find the way.

I'm new programming in TCL.


If someone can help I'll be very thankful.

Hi

[gray]# set[/gray]
[b]for[/b] {[b]set[/b] i 0} {$i<3} {[b]incr[/b] i} { [b]set[/b] a$i [i]"this is $i value"[/i] }

[gray]# retrieve[/gray]
[b]for[/b] {[b]set[/b] i 0} {$i<3} {[b]incr[/b] i} { [b]puts[/b] [[b]set[/b] a$i] }
