Can I write several Assembly instructions on one line?

Question

Can I write several Assembly instructions on the same line as I can do with most high-level languages. Or does each assembler treat this function differently?

Answer 1

Each assembler has its own syntax . Even Intel's syntax on x86 is actually not the same for different assemblers. Some examples

• Does FASM use Intel syntax?
• Differences in MASM / NASM
• ASM: MASM, NASM, FASM?
• Difference between FASM and MASM / TASM?
• How do I know if the build code has specific syntax (emu8086, NASM, TASM, ...)?
