Flow Control

Break [Level]	Will break out of an If/Then, While/Wend or Repeat/Until code block. If the optional Level is specified, will break out of that number of nested flow blocks.
Continue	Will skip directly to the start of the code block, skipping any statements between the Continue and the end of the code block
For <variable> = <expression1> To <expression2> [Step constant]	Defines a for loop, counting variable from expression1 to expression2, optionally incrementing by Step. The "To" value can be changed inside the loop.
Next [variable]	Increments variable and loops through the For loop again. Variable is optional and only included for readability
ForEach List() \| Map()	Loops through all of the elements in the specified list or map
Next [List() \| Map()]	Increments the ForEach loop. List() or Map() is optional and only included for readability
Gosub label	Send program execution to the code at label, and then the program will resume on the next time
Return	Returns to the code following the Gosub call.
FakeReturn	If Goto is used inside of a subroutine, you must use FakeReturn before the Goto
Goto label	Send program execution to the code at label
If <expression>	Starts an If block. The code inside the block will be executed if <expression> evaluates to #True.
ElseIf <expression>	An additional If inside an If block, evaluated if the previous If returned #False.
Else	The code following Else will be executed if all previous If and ElseIf expressions evaluated to #False
EndIf	Ends an If block
Select <expression>	Start a Select block and use the value of <expression> for the comparisons
Case <constant>[, ...]	Compares the value of the Select expression to <constant> and executes the following code block if it evaluates to #True.
Default	A code block to run if none of the previous Case statements evaluated to #True
EndSelect	Ends a Select block
Repeat	Begins a Repeat block. Unlike If or While, a Repeat block is always executed at least once.
Until <expression>	Ends a Repeat block. If <expression> evaluates to #False, will run the Repeat block again until <expression> evaluates to #True
ForEver	Ends a Repeat code block and turns it into an infinite loop. Will run forever until the app is killed or a Break statement is encountered
While <expression>	Begins a While code block. Will repeat the block until <expression> evaluates to #False.
Wend	Ends a While code block

Only use a single = in expressions, e.g. "If i=0". Do not use Then, which is not a keyword.

You can use ranges in Case statements, e.g. "Case 1 To 8"
