56 Usage Example
Example: branch destination of conditional branch instruction out of range
This example shows a branch outside the permitted range (-128 to +127 of PC) of a BCC LABEL con-
ditional branch instruction.
The source list is as follows.
The final list file after assembly is shown next. LABEL exceeds the permitted branch range of BCC LA-
BEL, so the code has been converted to BCS *+5, JMP LABEL. Note that the mnemonics and object
code are different.
