the if statement in TCL

Question

I have a question about if statement in tcl of the following code:

if {(($number == 1)&&($name == \"hello\")) || (($number == 0)&&($name == \"yes         


        

Answer 1

I think the error message you are getting does not mean that $number has to be a boolean (I got the message expected boolean value but got "$number == 1 && $name == "hello""). It means that the string $number == 1 && $name == "hello" is not a boolean value - which is definitely true. If you use curly braces in your if expression those strings are not evaluated but are simply interpreted as they are - as a string of characters.
