In Skype Leroy asked for examples of using LIST Style which would be FORMAT() codes Z(#) or Y.
My CIDC 2019 presentation showed how to use STYLE to implement a Checkbox column or an Icon column. What makes this possible is using Style to change the Column or Cell to the WingDings font. I uploaded this to Git.
IMO Style is a better way to implement LIST colors because it only takes one LONG so can result in much less generated code. Sorry I don’t have an example handy. If you have examples of using Style please post them.
