Associative Array from variables

Can somebody help me with a correct syntax  to create Associative Array from variables?

Now I have this:

 

a = {"a1", "a2", "a3"};
b = {"b1", "b2", "b3"};

AB = [
 "AA" => a,
 "BB" => b
];

AB["AA"];

It returns:

 

/*:

a

I want it to return:

/*:

{"a1", "a2", "a3"}

I tried different combinations of Eval List(), Eval Expr(), Expr() and Eval(), but no luck.

 

Thanks!

You almost had it!  You need to input the arguments to Associative Array() as Associative Array( keys, values ), instead of Associative Array( {keys, values} ),

 

a = {"a1", "a2", "a3"};
b = {"b1", "b2", "b3"};


keys = {"AA", "BB"};
values = Eval List({a, b});


AB = Associative Array(keys, values);

AB["AA"];

Re: Associative Array from variables

Had to go brute force way for now:

 

AB = Associative Array();
AB["AA"] = Eval List(a);
AB["BB"] = Eval List(b);

Re: Associative Array from variables

This does not produce the desired result. Keep in mind, keys are "AA" and "BB", and values for those keys are lists a and b, respectively.

But it got me on the correct track, so this works as intended:

a = {"a1", "a2", "a3"};
b = {"b1", "b2", "b3"};


keys = {"AA", "BB"};
values = Eval List({a, b});


AB = Associative Array({keys, values});

AB["AA"];

Thanks!

 

P.S. Actually it doesn't work either.

 

I can't understand how JMP decides which one to use if my values are lists too??

//Create an associative array from a list that contains two lists of a key-value pair:

map = Associative Array( {{"yes", 0}, {"no", 1}} );

//Create an associative array from a list of keys and a list of values:

map = Associative Array( {"yes", "no"}, {0, 1} );

 

Re: Associative Array from variables

AB = Associative Array(EvalList({a, b}))
