What inspired this wish list request? 

JMP provides many useful platforms and great functionality for exploratory data analysis.

But even after 18 versions of JMP - there is still some low-hanging fruit to be picked

- such as is in spec(value) 

What is the improvement you would like to see? 

For a column with Spec limits, please provide

1. a JSL function
   

   is in spec(:value)

   which compares the value of the current row with the spec limits of the column and returns 1 if the value is in spec,
   missing, if the value is missing
   and 0 if the value is out of spec
   
   

2.  a functions
   

   is out of spec(:value)

   which compares the value of the current row with the spec limits of the column and returns
   0 if the value is in spec
   missing, if the value is missing
   -1 if :value[] < LSL
   +1 if :value[] >USL

Both functions should be available via the right click "new formula column" menu.

Then users can easily generate new transform column on the fly in every platform - to group and add color to specific data points.

Why is this idea important? 

Is the value in spec is a question that is often asked. Right?
-> JMP users will love the new easy to use functions.

• "Select out of spec rows" (right click menu on column header)
• and then we could have a << Get out of spec rows which could be send to a column which would return missing if spec limits aren't set and empty matrix if they are set but there are no such values.
• Though, what would happen if we get the multiple spec limits which we have asked for for quite some time?

<< get out of spec rows :

Where(not(is in spec(:value)))

  One of THE arguments for an official function
  ... with an additional argument to specify which spec is used for the calculation.

maybe even some aggregation functions like:
- Col N in spec (:value, groupby)

- Col N out of spec (:value, groupby)

- Col N above USL (:value, groupby)

- Col N below LSL (:value, groupby)

?

.... and Tables/Summary, Tabulate and Graph builder Summary statistics ?

Hmm, maybe not ...
They can easily be broken down into

- Col Sum(is in spec(:value), groupby)

- ...

[hogi]

by the way: grouping
Where they should be added: header statistics
(here one cannot use custom, broken down code)

@Jeff_Perkinson 
the other issue we discussed yesterday.

This function will allow very cool custom transforms!
