Hello,

This isn't the question you asked, but since you mentioned $ZU functions, please bear in mind that:

• $ZU functions are deprecated
• $ZU functions are no longer documented
• Users are encouraged to replace $ZU functions with methods and properties in InterSystems class libraries that perform the equivalent actions

Your specific example, $ZU(67,15,$j), is replaced by ##class(%SYSTEM.Process).ClientIPAddress($j).

Best,

Aaron

Hello,

You may find it helpful to read through our product documentation on this subject matter:

http://docs.intersystems.com/latest/csp/docbook/DocBook.UI.Page.cls?KEY=...

The documentation covers some reasons why you might want to use it, and also describes how the behavior of this particular mode differs from a regular startup.
