C51 | RE: Hex file size ? Jon Ward Check the linker map file (.M51). It includes a table of the physical memory used by your application. DATA memory, CODE memory, and XDATA memory are listed here.

To determine the total size of your program, take the starting address of the last thing in CODE memory (0080H -- getkey in this example) and add its size (000Ah). This gives 008Ah which is the length of your program in bytes.
