I encountered an intriguing use of the switch / case statements and i'm wondering if it's a bug or if it's actually an alternative format? And which one is recommended?
case 'a': a=a-0.02**,**
But shouldn't it be the following, with a semicolon at the end, instead of a comma?
case 'a': a=a-0.02**;**
In Arduino IDE 1.8.9, i get no errors on both when verifying. But on Arduino - SwitchCase it is shown that the format should be as in the second example.
