Hi,

This may be a simple one. Consider the following.

set a 10
set b $a

Now I want to print the value of "a" using the variable "b". How can I
do this?

Thanks in Advance,
Prabu.


Hi,

in addition to the already proposed solutions, you can always use "upvar" to create sort of references to variables:

set a 10
upvar 0 a b

set b 17
puts $a; # output: 17
