Assembly Language is a non portable programming language consisting of instruction mnemonics used to form programming statements. There are 9 different opcodes for the TEST instruction depending on the type and size of the operands. x86 assembly language is a family of backward-compatible assembly languages, which provide some level of compatibility all the way back to the Intel 8008 introduced in April 1972. x86 assembly languages are used to produce object code for the x86 class of processors. and values instead of their 16-bit (ax, bx, etc.) This is the full 8086/8088 instruction set of Intel.
