Dynamic Creation of dictionary keys in CASL

buncket — Fri, 20 Sep 2019 02:51:47 GMT

Hi everyone,

I am trying to dynamically create a dictionary in the CASL. In this case I will not know the dictionary keys until I am iterating through an array creating the dictionary.

Below is example code of what I am trying to do with current output and what I want as an output.

proc cas;

count = {"one", "two", "three"};

do x over count;

print x;

temp_dic.x = "hi there";

end;

print temp_dic;

run;

Current output:

one

two

three

{x=hi there}

Wanted output:

one

two

three

{one = "hi there", two="hi there", three = "hi there"}

Obviously this is a simplified example, but the thing that I am trying to find out is to evaluate x and use as a dictionary key.

It seems odd that CAS evaluates x differently in side the loop. I also tried casting x as a string, and am all out of ideas.

Is what I am trying to do possible? or am I unable to resolve x inside the loop as a dictionary key?

Thanks!

Reading the documentation both the dot and bracket notation should work. I don't understand how the syntax for the dot notation would need to look like but it appears using brackets returns the result you're after.

proc cas;
  count = {"one", "two", "three"};
  do x over count;
    print x;
    temp_dict[x] = x;
  end;
  print temp_dict;
run;quit;

one
two
three
{one=one,two=two,three=three}
