It explicitly states that labels are case insensitive (page 79) and that machine instructions can be used in the operand field (page 82). So what I thought were questionable constructs are actually valid according to that assembler. If your aim is to be as compatible with old sources as possible, maybe it's worth perusing.J.B.Fri, 19 Jan 2018 05:14:22 -0000https://sourceforge.net/p/asm8080/bugs/8/?limit=25#8d9bhttps://sourceforge.net/p/asm8080/bugs/8/?limit=25#fa03You're right.. this code is not optimal.
