Abstract I have a function objectName that gets SymbolName and value. I would like to apply this to many variables at once with another function that applies to each argument with unknown number of them. I would prefer not to list them but just throw them in as arguments much like the function 'Plus[a,b,c,...]' but would output results as pairs in a list {{name[a],value[a]},{name[b],value[b]},{name[c],value[c]},...}. I cannot seem to get it to work.

objectName = Function[Null, {SymbolName[Unevaluated[#]], Evaluate[symbol]}, {HoldFirst}];
dataIn[#__] := Function[Null, objectName[#__], Listable];

This might work:

objectName = Function[Null,
  ReleaseHold[
   Map[
    Function[Null, {SymbolName[Unevaluated[#]] , #}, HoldAll],
    Hold[{##}],
    {2}
    ]
   ],
  HoldAll
  ]

Example:

a = 1;
 objectName[a, b, c, d]

{{"a", 1}, {"b", b}, {"c", c}, {"d", d}}

  • $\begingroup$ thank you but I need variable number of arguments to work for the dataIn[]. $\endgroup$

  • $\begingroup$ @Henrik-Schumaker yes of course. but it needs to work in the dataIn so it could create rows of name-value pairs for presentation of variables and their values. an auxiliary function dataOut would present the results of calculations in name-value pairs. $\endgroup$
