tcl: stop proc from continue

I wrote a script that need to work inside tool. When sourcing the file I want "checker" proc will drop the entire sourcing if $current > $exp The problem is a inner command inside the tool call "exit" and this command cause tool to exit. How can I implement it? I tried instead of "exit" use "error" but it print additional errors and don't stop my script clearly.

proc checker {} {
    set current 100
    set exp 50
    if {${current} > ${exp}} {
        exit
    }
}

checker 

puts "done!!"

A return statement in a script will stop sourcing a script.

When you're in the proc, you can use return -level <integer> to return not only from the proc, also from a higher level in the call stack.

This is equivalent to using the uplevel command to execute a command at higher level in the call stack.
