@FearMe2142 looking at this again, you can in fact accurately determine the height of the text you are going to print. You need to grab a table of fontMetrics and then add together ascent and descent to get the total line height. This means that you can, if you wish, keep the text together in a continuous string, which does simplify the code slightly. In the code below I’ve also added typewriter scrolling, so that what you’ve written doesn’t disappear off the edge of the screen or beneath the keyboard. I was also able to use ascent and descent to draw two lines, a thicker one for the text to “sit” on, and a paler one as the separator between each line. One disadvantage of this method compared with the above is that Codea doesn’t tell us where, horizontally, the block of text ends, so our cursor options are limited to text-based cursors, such as the below (so if you wanted, say, a cursor that was a different colour to the text, that’d take a rethink).
Edit: tidied up the code a bit

the only problem is if it back spaces back all the way it won’t let me type, but I’ll take a look at that after work. Thank you! And cheers!
