jsl script error

Pranadeep — Fri, 11 Apr 2025 03:52:54 GMT

Hi, I have 2 files(Limits and wat_combined). Limit file has the limits that i want to set to the same test in wat_combined file. My Jsl script is working as expected but the spec limit area of the column Please let me know how to fix that.
Jmp version: 18.2.0

After a quick look through the JSL, I have observed 2 items that may cause issue.

I am not aware of any function called Next(). You use it a couple of times in the code. It is a guess that it may be the function Break() that you are looking to use.
Around line 110 you are attempting to set the Spec Limits column property. In it you reference the memory variables of usl and lsl. The issue is that the references are within a JMP list {}. JMP lists are not evaluated prior to execution. Therefore, usl and lsl will not be evaluated. The easiest way to get the values evaluated is to use Eval( Evalexpr ())
```
Eval(
	Eval Expr(
		Column( dtData, dataColName ) << Set Property(
			"Spec Limits",
			{LSL( Expr( lsl ) ), USL( Expr( usl ) ), Show Limits( 1 )}
		)
	)
);
```
This will force the evaluation prior to actually executing the Set Property

Hi,
If you're running into scripting issues or just prefer a ready-to-use solution, there's a short tutorial with a JMP add-in showing how to handle spec limits and yield analysis without writing JSL:

https://www.youtube.com/watch?v=Nx5jWKAl7Z0
YieldOptiX is designed for test data workflows and it leverages JMP’s manage spec limits feature by also adding the ability to automatically find the best limits based on distribution parameters — either within or beyond predefined constraints.
Might be helpful if you're looking for a more streamlined approach.
