WebSep 27, 2024 · The absolute address jump opcode (FF /4) does not accept an immediate value. It can only jump to a value stored in a register or stored in memory.Therefore, using it will require you either: Storing the absolute offset at some reserved memory space, specifically allocated by the hook routine for each hook function for that purpose, or
Webinstructions. If a jump in a 16-bit mode program exceeds the range permitted by a signed byte offset, MASM generates a relative jump out of range error. Assuming that … WebBranches typically used for loops (if-else, while, for) Loops are generally small (< 50 instructions) Function calls and unconditional jumps handled with jump instructions (J-Format) Recall: Instructions stored in a localized area of memory (Code/Text) Largest branch distance limited by size of code Address of current instruction stored in the program
