a program. The value of the displacement
Counter (PC) and the next instruction is fetched from the location
designated by the new contents of the PC. This jump is measured from the
address of the instruction Op Code and has a range of-126 to +129 bytes.
The assembler automatically adjusts for the twice incremented PC.
To jump forward five locations from address 480, the following assembly
language statement is used
