怎么单独使用变量替换列表里面的值并计算

[#1]

lsl = 53;
target = 61;
usl = 69;

dataspec = Expr({ LSL( lsl ), USL( usl), Target( target ), Show Limits( 1 )});
dt:data << Set Property( "Spec Limits",Eval(dataspec ));

代码如上，但是始终不生效，规格线无法赋值，请求大家的帮助，感谢！

You will have to evaluate your values

Names Default To Here(1); 

dt = Open("$SAMPLE_DATA/Big Class.jmp");


lowlimit = 53;
targetvalue = 61;
highlimit = 69;

dataspec = EValExpr(
	{LSL(Expr(lowlimit)), USL(Expr(highlimit)), Target(Expr(targetvalue)), Show Limits(1)}
);

dt:weight << Set Property("Spec Limits", Eval(dataspec));

or you can do eval + evalexpr

Names Default To Here(1); 

dt = Open("$SAMPLE_DATA/Big Class.jmp");

lowlimit = 53;
targetvalue = 61;
highlimit = 69;

Eval(Eval Expr(
	Column(dt, "weight") << Set Property(
		"Spec Limits",
		{LSL(Expr(lowlimit)), USL(Expr(highlimit)), Target(Expr(targetvalue)),
		Show Limits(1)}
	)
));
