Minimum command set?

[Geoff Canyon]

I'm curious: what is the minimum set of commands/functions you need to 
know in revolution to be able to get started? Off the top of my head:

put...
put...into...
set the...of...to...
repeat with x = 1 to 10...end repeat
if...then...else...end if
button "someButton"
field "someField"
card "someCard"
stack "someStack"
on mouseUp...end mouseUp
on openCard...end openCard

What would you add?
