Lower Case Mnemonics
Posted on

Why do so many 6502 coders nowadays write their code in lower case?
I'm not judging anyone for doing it, but personally, I dislike it when I see:
lda #$00
sta $d020
instead of:
LDA #$00
STA $D020
Back in the day, going by the
Commodore 64 Programmer's Reference Guide
(one of many quotable examples), 6502 was almost always written in upper case, as per this page from the said guide:

One theory I have is that since many if not most other computer languages today are popularly written in lower case, it has seemingly become de rigeur to apply
the practice to coding 6502.
And for the record, this website that you are reading these words on, for instance, is coded with
HTML,
PHP,
JavaScript and
CSS, all of which I write in lower case, but there is
no law against writing web markup in capitals either.
