The limited range of branches (-128/+127 locations) is more than adequate for most (but not all)
situations. In cases where this range is too short, a jump instruction must be used. For every branch
there is a branch for the opposite condition so it is a simple matter to replace a branch which has
an out-of-range destination with a sequence consisting of the opposite branch around a jump to the
out-of-range destination. For example, if a program contained the instruction...
where TINBUK2 was out of the -128/+127 location range, the following instruction sequence could
be substituted...
Branch if Carry Clea
Branch if Carry Set
Branch if Equal Zero
Branch if Greater Than or Equa
Branch if Greater Than
Branch if Higher
Branch if Higher or Same (same as BCC)
Branch if Less Than or Equa
Branch if Lower (same as BCS)
Branch if Lower or Same
Branch if Less Than
Branch if Minus
Branch if Not Equal
Branch if Plus
Branch if Bit(s) Clear in Memory Byte
Branch Never
Branch if Bit(s) Set in Memory Byte
Branch if Overflow Clear
Branch if Overflow Set
