The exit command is a useful way of making the flow of code very clear, but it only works with DO or FOR loops. But it may not have occurred to you that you can in fact use it instead of downward pointing gotos, in any code that has a straight line path. Just implement a single-shot DO loop around the code:
Sadly the parser expects a variable in the test so you can't use 'until 1=1' or 'until 1' as you can with other languages. But it can help make your code clearer than a string of elseifs or whatever.
Code:
symbol F_one = bitx
F_one = 1
Do
if x then:... exit:endif
if y then:... exit:endif
if z then:... exit:endif
loop until F_one = 1
