Can anyone verify?

I'm using PBP 2.60 and reading the manual: Copyright ©2009 microEngineering Labs, Inc. Oddly, the PDF version of the manual I'm using doesn't (at least readily) identify the software version.

Anyway, to the point: In the DATA statement section a label is described:

{Label} DATA {@Location,}Constant{,Constant...},

but in the READ statement section, no description of this feature is described or demonstrated.

READ Address,{WORD}{LONG} Var {,Var...}

... is this one of those "undocumented features" that I read about occasionally or am I missing something? I have tried using the label in the DATA statement and it compiles fine, but in the read it gives errors (as I'd expect it to work). Is there, perhaps some syntax I haven't tried? Older posts refer to (and demonstrate) it, perhaps it is no longer implemented?
