Continue and break from repeat loops

[Ultron14@...]

Hello,
    
    I am new to this list, and no doubt this subject has been beaten to 
death, but it is there any way for pre Lua 4 to break out of a while loop? 
How about  a 'continue' command that goes to the top of the loop. Are there 
any ways of implementing this in Lua 3?
    As far as wish list stuff goes...GOTO statements would be ideal, you 
could of course accomplish all of the above and more with that!

Thanks,
Jules
