Hi everyone (but probably mostly Shallan),

I'm looking at the amazing examples Shallan shared on their Github and learning a lot!

I am confused about one particular thing in the Nybble Mode example and I was hoping for some illumination. On lines 189, 206, and 211 there's instructions followed by variables but then a colon (:) and an additional hex value. For example, on 189:

ldz rowsToDraw:#$02

At first I thought it was maybe a pseudocommand for ldz from the version of KickAssembler that's needed for the MEGA65 support, but then it's also used with ora and lda which are standard 6502 instructions.

Thoughts?

This is an inline label. Allowing to reference the value of an instruction directly rather than having it before the instruction and using label+1

Ahh, brilliant! Thanks for the reply, Shallan! I'm familiar with 6502 from working on NES where the code is in unwritable ROM so self modifying code still catches me off guard :)
