working with variables

[pankajpanjwani]

Hi Experts,
I have a code like

set abc 1
set def 1
set xyz 0
...
...

foreach x { abc def xyz } {
if { <value of variable $x> != 0} {
perform this
} else {
perform this
}
}

In this by <value of variable $x> I mean that I would like to have value 0 or 1, depending upon variable &quot;abc&quot;/&quot;def&quot;/&quot;xyz&quot;

I am unable to make TCL subsitutue the value of variable in the &quot;if&quot; condition.

Do you have any solution for this.
thanks for reading and problem and thinking on problem.

[ulis]

  set abc 1
  set def 2
  set ghi 3
  foreach v {abc def ghi} { puts [set $v] }

An other way:

eval puts $v

but eval is not easy to master so the first way is better.

Good luck!

thanks ulis,
This worked, I tried almost evrything except this
Anyways, thanks and your right eval looks to be simple but it's more complex to master.
