Tcl set Problem

Tcl set Problem

Tcl set Problem


I want to assign to the "data" variable the content of "test$i_input", where "i" is an index variable, for example i= 0 to 5.

>set i 0
>set test\$index_input 33

But I have the next error:

>set data $test\$i_input
can't read "test": no such variable

How I can do correctly this assignation?


RE: Tcl set Problem


You are messing with 3 variables ( i, index_input and i_input ) in your sample code, so is possible to misunderstood your intention, but I think this is what you want :

CODE --> Tcl

set index_input 22

set test$index_input 33

set data [set test$index_input] 
Here the variable that stores value 33 is called test22.
