Assuming tn_shell is a bourne like shell, you can probably do:

a13=$( echo "$a12" | tr a-z A-Z )

or

a13=$( echo "$a12" | tr [:lower:] [:upper:] )

That's shell, not Tcl… – Donal Fellows Feb 14 '14 at 13:55
Is `tn_shell` a Tcl shell? Googling `tn_shell` is not at all useful, but does tell me where to get petrol in Tennessee! – William Pursell Feb 14 '14 at 14:17
I've no idea, but the question _is_ tagged… (Tennessee; hmm, I've changed planes there…) – Donal Fellows Feb 14 '14 at 20:36

a="$(tr [a-z] [A-Z] <<< "$a")"

bash-3.2$echo lower to upper | tr '[:lower:]' '[:upper:]'
LOWER TO UPPER  

To Save in the variable use below
var=$(echo lower to upper | tr '[:lower:]' '[:upper:]')

That's shell, not Tcl, and doesn't actually deal with values in variables… – Donal Fellows Feb 14 '14 at 13:56

To turn a string into upper case, use string toupper. That returns a copy of the input string (with the case transformation applied, of course) that you can then assign to wherever you want.

set a13 [string toupper $a12]
