Implement some sort of untill() function?

[Blob 92]

Ive been working on some stuff and would find a function that stopped an if()/elsif() statement when something happens, e.g:

if(Button){
     Height++
}untill(Height = 30)

I know it can be done by doing this:

if(Button & Height < 30){
     Height++
}

But there are some cases where it would be easier for some sort of untill() function.

while(Height < 30) {
     if(Button) {
          Height++
     }
}

Lol, I completely forgot about the while() functions :P Thanks

while(Height < 30) {
     if(Button) {
          Height++
     }
}
