Hi Everyone,
I have created a function in assembly language, that gives a warning "(863) : WARNING (435) Offset has exceeded its range - JR Instruction replaced". Kindly let me know the reason for this warning and what can I do to get rid of this warning.

Regards,
Nick.

Sample code of the function is as following.

The warning appears at
JR Z,L_43

Nick,
The JR instruction is "Jump Relative" and uses a signed 8 bit offset.
The maximum offset is 129 bytes forward (0-128) and 128 bytes backwards.
The warning just informs you the offset is greater than what is allowed, so the instruction is replaced with a JP instruction, which uses 16/24 bit addressing.
