SET_FREE_HEALTH_CARE

This opcode sets a free hospital visit for the player. When enabled, if the player is wasted, he will not lose any weapons or cash after respawning. The free treatment works once only, so to allow free treatment again, you have to enable it through this opcode again. This opcode was never called in the original script of GTA III. The value set with this opcode is saved in block 16 of the save file in GTA III, block 18 in Vice City, and block 15 in San Andreas.
