newbie...Want to loop statements until <time>

[ilcaa]

i have 2 questions...

I have programmed in Visual Basic and this languages seems to be missing some functions i have used before like Do Until, While, etc...  I am trying to create a loop that runs until a specific system time is reached, say, 3:00 PM.  

also, is there a way to attach a "exit macro" keyboard shortcut to stop a macro from running? if not what is best practice..

thanks on both questions...
