//
// Initialization script for the scene is PART02.PRC's 26th script (011_INIT)
// and the background used in the scene is L11.PI1. The difference between
// the PC version and the Amiga/Atari ST version of the script is that the
// PC version calls scripts 37 and 36 for handling movement of the character
// when Amiga/Atari ST version calls scripts 22 and 21 for the same purpose
// (Scripts 37 and 22 handle vertical movement, 36 and 21 the horizontal).
//
// The called scripts only differ functionally so that all BREAK opcodes have been
// doubled in the Amiga/Atari ST versions (i.e. one BREAK has become two BREAKs)
// and in script 21 after LABEL_25 there's an extra opcode that isn't in script 36:
// SET globalvars[251], 0.
//
// As a BREAK opcode stops the execution of a script it causes a pause and
// with the BREAKs doubled the pause is twice as long in the Amiga/Atari ST versions.
// Thus the longer pause is eliminated by running only one BREAK when several
// are designated (i.e. ignoring a BREAK if there's another BREAK after it).
