Unix version of gosub or goto??

Is there a Unix (Solaris v8 ksh) version of the old basic command gosub or goto? I've researched the return command, but can't identify the command to return from. I am not trying to return from a function. Can someone give me a basic understanding of this please? Thanks so much in advance for any help.

ksh has no goto

return is used to return from a function. And invoking a function is very close to gosub.

Most of the time when I need "goto" functionality in ksh, I do something like this:

function foo 
{
    # Assume a successful exit code
    typeset RC=0
    # Create a cheesy, endless loop
    while :
    do
        ...
        if [ some test condition]
        then
            # Set some flag if necessary
            RC=1
            break
        fi
        # Don't want any more loop iterations
        break
    done

    return ${RC}
}

Thanks fellas, looks like I'm function city bound. Shouldn't be to hard to adjust my thinking into the java type of lifestyle.
