Join two strings to form a file name in TCL

Question

I cant get this to work .

set dut xyz
set fname [join {$dut "-CE"} ""]

But This works :

set fname [join {xyz "-CE"} ""]

I want fname as "xyz-CE"

Answer 1

Try the following

set dut xyz
set fname ${dut}-CE

Normal word concatenation doesn't need a join.
