Write Assembly code (8086) that implements the function of (A.B) +C..pdf
0 likes14 views
The document contains assembly code for the 8086 architecture that implements a function to calculate the expression (a.b) + c. It includes a macro for a cursor positioning routine 'gotoxy' that communicates with BIOS interrupts to set the cursor position. The code is structured to support both DOS and Windows environments with appropriate calling conventions.
