Another JScript eval bug

[Bryan Mills]

According to MSDN: "new variables or types defined in the
eval statement are not visible to the enclosing program."

However, in some cases under IIS 5, this is not the case.
Try the following program:
eval("var z = 12; 5;");
Response.Write(z);

According to the documentation this should be an error;
however, it prints "12".

eval is the root of all evil, take it away....


[IE clientside tested:]

a=eval("z = 12");
document.write(a); // 12


a=eval("var z = 12");
document.write(a); // undefined
