The MXSCallstackCaptureEnabled context allows you to better control how the MAXScript call stack is captured, which can aid in debugging. With deep stacks and/or lots of arrays, big structures, etc present in the call stack, doing a stack capture can be an expensive operation. When this context is set, the mxs call stack is not captured if a mxs runtime exception is thrown. Available in in 3ds Max 2017 and higher.

For example:

Instead of:

try (setproperty obj #prop val)
        catch() -- just eat any errors

You can use:

try with MXSCallstackCaptureEnabled off (setproperty obj #prop val)
        catch() -- just eat any errors

or

with MXSCallstackCaptureEnabled off try (setproperty obj #prop val)
        catch() -- just eat any errors

or

with MXSCallstackCaptureEnabled off 
        (
             try (setproperty obj #prop val)
                catch() -- just eat any errors
        )
