		+	== The language ==
		+
		+	The field script language in ff8 is a simple assembly language with a stack. Here is an example:
		+
		+	stack = []
		+
		+	PSHM_W 1024 # push var1024 onto the stack (stack = [var1024])
		+	PSHN_L 6 # push number 6 onto the stack (stack = [6 ; var1024])
		+	CAL EQ # compare the two numbers at the top of the stack, pop this numbers, and push the result (1 or 0) into the stack (stack = [1 or 0])
		+	JPF LABEL1 # if the popped top of the stack is 0, jump to LABEL1
		+	PSHN_L 0 # push 0 at the top of the stack (stack = [0])
		+	POPM_W 1024 # pop the top of the stack into var1024 (stack = [])
		+	JMP LABEL2 # goto LABEL2
		+	LABEL1
		+	PSHN_L 1 # push 1 at the top of the stack (stack = [1])
		+	POPM_W 1024 # pop the top of the stack into var1024 (stack = [])
		+	LABEL2
		+	...
		+
		+	In standard code, it's equivalent to:
		+	if(var1024 == 6) {
		+	var1024 = 0;
		+	} else {
		+	var1024 = 1;
		+	}
