Write a subroutine called REPLACE that processes a null-terminated string of decimal characters and replaces leading zeros with spaces. Pass the 32-bit address of the string to the subroutine in register BX.

This is an intel 8086 assembly problem, there are many answers here that are all wrong, please don't use registers that are not in 8086 (EAX(32 bit) or RAX (64 bit)) Only use 16 bit registers, and please do it in Intel 8086.
