Re: st: renaming variables from first observation |

Yes Nick, precisely, my values in the first observation were not legal. What I meant by storing values in a macro was something like a horizontal -levelsof- command. Once I obtain the values in a single macro I thought of simply using your and Jeroen Weesie's -renvars-. But the map option seems not that easy to understand, perhaps because I find `quotes' confusing sometimes. One needs to have a string expression in the parentheses while using the map option but I see that the expression in your example is in `quotes', normally used for macros. Would be really great if you could clarify this fundamental issue.
