If I want to say that dy/dx is calculated at z

then in latex I can write

\frac{dy}{dx}\Big|_z

The \Big is to scale | according to the size of the \frac.

I am using newmat and amsl modules that have supported the native math mode commands till now. But context does not recognise \Big.

What is the native context way of doing this?

MWE (in case its needed)-----------

\usemodule[newmat] \usemodule[amsl]

\starttext \startformula \frac{dy}{dx}\Big|_z \stopformula \stoptext

In MkIV, you don't need the newmat module and amsl module is deprecated in both MkII and MkIV.

\starttext \startformula \left.\frac{dy}{dx}\right|_z \stopformula \stoptext

Thanks Aditya. Need to read manuals more carefully.
