Used by the routine at 657F.

|
This routine saves the state of the execution of the game's main BASIC, which is used immediately after the loading routine is executed. The RET at the end returns to BASIC, which is positioned at a "GOTO 1" statement that re-runs a program. The loading system picks up the system variables to match this state, which allows the game to start when it's loaded.
