Hi Guys, i´m trying to asemble a routine that contains a jmp table, but it is exceeding 8 bytes, and this error came up:
FbRtl.asm(8115) : error A2075: jump destination too far : by 8 byte(s)
I tried to use the LMP command, or even used two "::" on th destination labels, but it keeps showing the error. How can i assemble this ?
