WebAn ASM file is a program written in the low level programming language known as assembly language. It is primarily used for writing hardware related code such as for programming micro-controllers. Program is written using simple assembly language syntax that includes operators and operands to carry out different operations. WebMPASM assembler supports the following radix forms for constants: hexadecimal, decimal, octal, binary, and ASCII. The default radix is hexadecimal; the default radix determines what value will be assigned to constants in the object file when a radix is not explicitly specified by a base descriptor.

WebIn addition to supporting referring to memory regions by labels (i.e. constant values), the x86 provides a flexible scheme for computing and referring to memory addresses: up to two of the 32-bit registers and a 32-bit signed constant can be added together to compute a memory address.
