@IstvánZachar, you need to keep both the symbol and the rhs unevaluated (pls see belisarius's comment). For the form you suggest prntHF2[a] gives 2 (rhs is evaluated) when az=1.

@Kguler, can you please say some words on why to use OwnValues and not simply: Attributes[prntHF2] = {HoldAll, Listable}; prntHF2[sym_Symbol] := Row@{HoldForm@sym, " = ", sym}?

| Apr 27, 2012 at 5:52 | comment | added | Dr. belisarius | mmm does not work if you set az=1 | |

@Andy, thank you for the vote. Actually, I was just thinking about OwnValues the same way :)

HoldForm is a very useful trick for this sort of thing. I'm surprised my own answer didn't include it :) +1
