13.3 Number Registers Used in mm

Table 13.1 lists mm 's number registers. A dagger ([dagger]) next to a register name indicates that the register can be set only from the command line or before the mm macro definitions are read by the formatter. Any register having a single-character name can be set from the command line with the -r option.
