WebThe SpectNetIDE assembler provides you a powerful way to declare macros, and apply them in the code. While in most programming languages and assemblers the macros are preprocessor constructs and use simple text replacement, the SpectNetIDE implementation is different. Unlike in C, C++ (and some Z80 Assemblers), SpectNetIDE macros emit … WebApr 2, 2024 · In this example, we used R1 register to set the loop of 5 times.

TI-85 Assembler Programming - Loops using DJNZ

WebDescription: DJNZ decrements the value of register by 1. If the initial value of register is 0, decrementing the value will cause it to reset to 255 (0xFF Hex). If the new value of register is not 0 the program will branch to the address indicated by relative addr.If the new value of register is 0 program flow continues with the instruction following the DJNZ instruction. http://www.z80.info/lesson3.htm

The Z80 has an instruction RLD, which apparently treats the lower 4 bits in the accumulator and the full 8 bits in (HL) as a twelve bit integer which it then rotates left by 4 bits. The carry flag does not participate in the rotation and the rest of the accumulator is left alone. Correspondingly, there's an RRD. coldworking glass cold working glass techniques
