print 打印后面的字符串、数值、变量的值等等. 项和项之间用逗号隔开, 最后加分号.

例子:  

print "Hello World!";

print a, b, c, "\n", a+b, b*c;

>> :mode clox
> print "Hello World!";
Hello World!> var a=2, b=3, c=a*b;
> print a,b,c,"\n", a+b, b*c;

println 的功能基本等同于 print, 不过会在最后加上换行.

println "Hello World!";
Hello World!

println a,b,c,"\n", a+b, b*c;
