Question - Can I call a :Block and return nothing?

[Bytebait]

How can I return nothing? (( I'm sorry, I don't know what to call these little blocks of code :ThisBlock . )) I took QBasic 45 years ago and dont remember. Anyhow, how can call a block , but if nothing needs to be done then the initial block will carry on? Unless this is failing because of something else? Thank you guys!

[CODE title="example"]
Sub Main
:Start
/goto o_I_Need_To_Do_Something
/delay 5s
/goto :Start


o_I_Need_To_Do_Something
/declare mobcount = ${Me.XTarget}
/echo Mobcount is ${mobcount}

/if (mobcount > 0){
/emote Time to get our hands dirty
}else{
/echo yeah... do nothing.
}


[/CODE]

This is old macro code (with even older styling (goto)).

I'd suggest using Lua instead

Well the basics of a macro function is

Sub NameOfSub
    |Body of Code here
/return

If you don't have a return, then the function will never return to where it was.
In the case of Sub main a return will end the macro. Failure to return would result in an error. So technically speaking you can, but it results in an error.

With that said.
:Start
o_I_Need_To_Do_Something are both /goto tags. None of those are reasonable to use here. You should use a function, and you should use while loops. goto is not the "correct" way to do just about anything ever.

Sub Main
    /declare mobCount int outer 0
    /while (1) {
        /call DoINeedToDoSomething
        /delay 5s
    }
/return

Sub DoINeedToDoSomething
    /varset mobCount ${Me.XTarget}
    /echo mobcount is ${mobCount}
    
    if (${mobCount} > 0) {
        /emote Time to get our hands dirty
    } else {
        /echo yeah... do nothing.
    }
/return

Now that I've hastily written an example of what it would look like done differently. I suggest considering investing time into learning Lua instead of macro language. I'm sure others will chime in with the same sentiment.
