Specification for an assembly language program

Reference no: EM1379054

Question: Require help with completing the following specification for an assembly language program. This is a practice question. This is part of an overall project that I am stuck at.

The program needs to check the current disk drive and report:

The drive letter which would normally be assigned by DOS
The amount of used space on the disk
The amount of free space on the disk
An indication that disk re-organisation is advised if the free space falls below 10% of the total available space.

Any naming conventions for program labels, sub-programs, variable names etc can be used.

Please could each line in the source code be documented with a remark explaining what it does so that I can understand it.

I would like the program to include:

Data transfer
Arithmetic & logical operations
Conditional and unconditional branching
Immediate, direct and indexed memory addressing
Sub-programs, macros and function calls
The program once assembled should operate as a .COM file
