<ILLEGAL VALUE> when trying to call $ZF("GETFILE") on OpenVMS
Per the information at http://docs.intersystems.com/latest/csp/docbook/DocBook.UI.Page.cls?KEY=... I am trying to use a call to $ZF("GETFILE") to obtain information about an OpenVMS file. But I get an <ILLEGAL VALUE> error.
For example:
w $zf("GETFILE",filename,"UIC")
reports:
<ILLEGAL VALUE>
My filename variable contains the full path and name of a file that I own. I hold the %All role in Cache.
This is 2012.1.5 on OpenVMS/IA64 V8.4
Any ideas what's going wrong?
