85 * ZMAIN API JUMP FUNCTIONS
86 *
87 * If the MINIMIZE_ROOT compile flag is defined, ZMAIN API functions
88 * are implemented as "jump functions" located in the ROOT segment,
89 * as expected by the NWK object libraries. This allows the actual
90 * ZMAIN function bodies to locate outside ROOT memory, increasing
91 * space for user defined constants, strings, etc in ROOT memory.
92 *
93 * If the MINIMIZE_ROOT compile flag in not defined, the ZMAIN API
94 * functions are aliased to the similarly-named function bodies and
95 * located in the ROOT segment with no "jump function" overhead.
96 * This is the default behavior which produces smaller overall code
97 * size and maximizes available code space in BANK1...BANK3.
