Looping Dialplan With Labels

Will goto work if the label appears above it? In the example below, the caller doesn’t press 1, I want them to loop up to the tryagain label. I wasn’t sure if the system would go back up in the dial plan or if its only going to look down. I am not in a place where I can test this myself. Does anyone know? Thanks for any insight you can provide.

exten => s,n,Set(ATTEMPTS=1)
exten => s,n(tryagain),GotoIf(["{ATTEMPTS}" = “4”]?optedno)
exten => s,n,Read(ALTCALLBACKID,custom/enteraltnumber,10,n,3,15)
exten => s,n,Playback(custom/youenterednum)
exten => s,n,SayDigits({ALTCALLBACKID}) exten => s,n,Read(ALTID,custom/callbackconfirm,1,n,3,15) exten => s,n,GotoIf(["{ALTID}" = "1"]?altidconfirmed) exten => s,n,Set(Attempts={MATH({ATTEMPTS}+1,i)}) exten => s,n,goto(tryagain) exten => s,n,Set(CALLBACKNUM={ALTCALLBACKID})
exten => s,n,GotoIf(["{ALTID}" = “1”]?buildcallfile)

Dialplans are fully fledged programming languages, even wihtout the use of While().

Thanks for replying, but I am not sure if that is a yes or no to my question. Asterisk is my first, for now, language that I do anything like this for. It’s great, and has been fun to learn on. Looking into Python next, to combine with Asterisk.

You can implement loops without using While().
