My suggestion is that you import the spec limits as column propery, independent from the Distribution Platform. then when you run the platform, you specify,

```
Distribution(
Continuous Distribution( Column( :NPN1 ),
Capability Analysis( 0 ) )
);
```

Examples of all elements availabe to any of the platforms is available in the scripting index

Help==>Scripting Index

I suggest you familiarize yourself with it. It is the answer to most of your questions.

An example:

```
Names Default To Here( 1 );
dt = Open( "$SAMPLE_DATA\Big Class.jmp" );
USL = 70;
LSL = 55;
Eval(
Substitute(
Expr(
:Height << set property( "spec limits", {LSL( __LSL__ ), USL( __USL__ ),Show Limits(1)} )
),
Expr( __LSL__ ), LSL,
Expr( __USL__ ), USL
)
);
Distribution( Continuous Distribution( Column( :height ), Capability Analysis( 0 ) ) );
```
