TEX parameters

The TEX parameters determine how much memory is allocated for various arrays used by TEX and INITEX. Note that mem_max is temporarily set to mem_top whenever you run INITEX. Comments in the Default file indicate the possible range of values for each parameter. The Default values are suitable for small to medium-size TEX documents. If you decide to increase one or more of these parameters then you may need to increase 's application memory size (via ``Get Info'' in the Finder's File menu). Note that a change to mem_top, hash_size, hash_prime or hyf_size will require rebuilding all format files; see section [*].
