WebIf you are actually using the nasm assembler (which is Intel format, not AT&T), then the times directive will work, as avinash indicated, as long as you want to predefine the data in either the .text or .data section. However, if you need to reserve bytes in the .bss section (in nasm ), you can use the resb (reserve byte) directive: WebDefining Data in Assembly Language Data Types Assembly language defines intrinsic data types, each of which describes a set of values that can be assigned to variables … tennis forehand topspin

WebFeb 11, 2024 · Data Registers: Data registers are used for arithmetic, logical and other operations. There are four data registers as listed below. EAX, EBX, ECX and EDX It is possible to use a 32-bit register and access the lower half of the data by the corresponding 16-bit register name. For example, the lower 16 bits of EAX can be accessed by using AX. WebData could be of a byte size, word or doubleword. SCAS − This instruction compares the contents of a register (AL, AX or EAX) with the contents of an item in memory. Each of the above instruction has a byte, word, and doubleword version, and string instructions can be repeated by using a repetition prefix.
