A dilemma is that if you quote code directly using the block quote function it appears as what it is coding for.
To solve this:
Tap the blue key three times to open a code block and press enter to get to the next line.
Copy-paste / write the code you want to use.
Press enter for a new line again.
Then tap the blue key three times again to close the code block.
Credit to lll for the instructions. Thanks, @lll.
