I'm confused by your example. Why would two assignment statements not generate two writes? (They do on my cc65 anyway.) Do you mean if there was only one of those lines? The example I had posted using [] generates a dummy read then the write, not explicitly in the assembly output, but implicit as part of STA (zp), Y. -- Brad Smith ---------------------------------------------------------------------- To unsubscribe from the list send mail to majordomo@musoftware.de with the string "unsubscribe cc65" in the body(!) of the mail.Received on Wed Oct 17 23:29:16 2012
