Answer / Jitendra Kumar Paswan

In 8085 assembly, you can't directly change data values like 74H to 47H. However, you can write a program to perform such an operation by using a subroutine that compares the current value with the desired value (74H) and updates it if necessary. Here is a simple example of how you could do this:

MOV A, H ; Load the current value into Accumulator A
CMP A, 74 ; Compare Accumulator A with 74H
JZ CHANGE ; If equal (Z flag set), jump to 'CHANGE' label

; Rest of your program here...

CHANGE: ; This is the label where we change the value
MOV H, 47 ; Load 47H into Higher Half Accumulator

; Continue with rest of your program...
