Some examples contain macros, so it is advisable to use Shift + F8 hot key to Step Over (to make macro code execute at maximum speed set step delay to zero), otherwise emulator will step through each instruction of a macro. Here is an example that uses PRINTN macro:

20 wrz 2024 · The 8086 instruction set is a group of commands that the Intel 8086 microprocessor uses to perform tasks. It includes a variety of instructions that allow developers to create software for many different tasks, from simple math to more complex processing.
Complete 8086 instruction set Quick reference: Operand types: REG: AX, BX, CX, DX, AH, AL, BL, BH, CH, CL, DH, DL, DI, SI, BP, SP. SREG: DS, ES, SS, and only as second operand: CS. memory: [BX], [BX+SI+7], variable, etc...(see Memory Access). immediate: 5, -24, 3Fh, 10001101b, etc... Notes:
The x86 instruction set refers to the set of instructions that x86-compatible microprocessors support. The instructions are usually part of an executable program, often stored as a computer file and executed on the processor.

When compiler process your source code it searches the emu8086.inc file for declarations of the macros and replaces the macro names with real code. Generally macros are relatively small parts of code, frequent use of a macro may make your executable too big (procedures are better for size optimization).
Description: The MOV instruction is the most important command in the 8086 because it moves data from one location to another. It also has the widest variety of parameters; so if the assembler programmer can use MOV effectively, the rest of the commands are easier to understand.
