Iterate through lines of text

I want to set an array with text then iterate through it - all the tutorials and posts I'm seeing about arrays are over my head or off topic. I know I can do this manually with a long slew of events but I'd rather do this with an array and an expression. I just don't know where or how.

for example - at 5 seconds:

"good start"

at ten

"keep going"

at fifteen

"almost there"

etc - thanks!

You can use TokenAt() to retrieve part of a string so long as there is a delimiter.

For example, if you have a string "M1,M2,M3"

then tokenat(string,2,",") will give you "M2"

Yeah tokenat definitely.

With array it's a pain 'cause you have to set each lines with one action

Array: set value at (0) to "good start"
Array: set value at (1) to "keep going" 
etc

Global text dialog = ""
System: Start of layout
  -> Set dialog to [insert your tokenized text]

dialog = "good start
keep going
almost there"
