Roku SDK Documentation : Statement Summary

BrightScript supports the following familiar looking statement types:

If / Then / Else If / Else / End If
For / To / End For / Step / Exit For
For Each / In / End For / Exit For
While / End While / Exit While
Function / End Function / As / Return
Print
Rem (or ')
Goto
Dim
End
Stop

BrightScript is not case sensitive.
Each statement's syntax is documented precisely later in the manual.

function Main() as Void 
	dim cavemen[10] 
	cavemen.push("fred")
	cavemen.push("barney")
	cavemen.push("wilma")
	cavemen.push("betty") 
	for each caveman in cavemen
		print caveman
	end for 
end function

Each line may contain a single statement, or a colon ( : ) may be used to separate multiple statements on a single line.

myname = "fred"
if myname="fred" then yourname = "barney" : print yourname
