Getting Logs of Console in Variable in TCL

Is it possible to get logs generated by one function in variable without returning that value from that function in TCL like what "$" used to be do in BASH.

function f1 {
    echo "ABC"
    return 0
}

Calling procedure is,

var=$(f1) ;# gives output ABC

What i know about how to solve this problem is, 

proc f1 {} {
    return "ABC | 0"
}

At the time of calling i need extract both value like,

set console_msg [lindex [split [f1] "|"] 0]
set retval [lindex [split [f1] "|"] 1]

Is there a proper way to do it in TCL?

Thanks,

This may seem obvious to you in hindsight:

set value [f1]

and to assign to variables:

lassign [split $value |] msg val
