4.3.4.7 Relocation Forms
Device-specific forms describe how a memory location should be patched by the linker. Forms are a
combination of functions, operators, and constants which completely describe how a memory location’s
value will be calculated from relocatable symbols. A conforming assembler should generate the relocation
forms described in this section.
Typically, it takes more than one form to encode an average instruction. For example, the group F5
requires four member forms to completely describe how the instruction in (5) should be patched when both
of its operands are external.
