帧上的ＡＳ：
display = "0";
stop();
function getdigit(digit) {
if(clear){
clear = false;
decimal = false;
display = "0";
}
if(length(display)<13){
if(display == "0" and digit != "."){
display = digit;
} else {
display = display+digit;
}
}
}
function getoperator(sign){
if(operator == "+") {
display = Number(operand)+Number(display);
symbol = operator;
}
if(operator == "-") {
display = operand-display;
symbol = operator;
}
if(operator == "*") {
display = operand*display;
symbol = "x";
}
if(operator == "/") {
display = operand/display;
symbol = operator;
}
operator = "=";
clear = true;
symbol = " ";
decimal = "false";
if(sign != null){
operator = sign;
if(operator == "*"){
symbol = "x";
} else { symbol = operator;}
operand = display;
}
}
按钮上的：
＂１＂
on(release,keyPress"1"){getdigit("1")}
＂２＂
on(release,keyPress"2"){getdigit("2")}
＂３＂，＂４＂，＂５＂，．．．．．．，＂０＂同上！
＂+＂
on(release,keyPress"+"){getoperator("+")}
＂－＂
on(release,keyPress"－"){getoperator("－")}
＂Ｘ＂，＂/＂同上．
＂Ｍ+＂
on(release){
memory = memory+Number(display);
symbol = "";
mem = "M+";
}
＂ＭＲ＂
on(release){display = memory;}
＂ＭＣ＂
on(release){
memory = 0; mem = " "; display = "0";
operator = ""; operand = false; clear = false;
decimal = false;
}
＂Ｃ＂
