Convert a list of symbols with value as a local variable.

cessej

I have given with a list of symbols with a value. What I want is to be able to call/use the symbol as a variable. What function do I need to convert a given list as a variable? Also these variables are local only to the given user function.

procedure(myFunc()

myList = list( list('varA 1.0) list('varB 2.0) list('varC 4.0))

; what function do I need to convert the given list as a variable?

;; also these variables are local only inside this function.

varC=varA + varB   ;; varC having value of 3.0

println(varA + varB)  ;; expected output is 3.0

 )

  • I don't think is this is a particularly good thing to do, because it relies on run-time evaluation, but you could do:

    apply('let cons(myList '(
      ; put your statements to evaluate within the quoted list
      varC=varA+varB
      println(varC)
    )))

    I would question why you are doing things this way, and whether there might be a better approach than building a list of variables and values and then trying to treat them as local. The beauty of SKILL and LISP is that this is easy to do, although it may not be the right thing to do...
