Challenge with Variables while using Memory Group by.

Hi,

Thanks in advance for your support. Hope I have a challenging issue now. Let me explain it here.

The input file contains column STATUS having values either 10100, 10102 or 10103. Now using Memory group by function I need to find the count of rows for each status and set them as variable so that i can use it in some other transformation and I have done it. Please check the transformation attachment.

Example
Status Count
10100 10
10102 5
10103 2

To show the above statistics in a file, i am using the following java script,

CNT_10100 = getVariable("10100","0");
CNT_10102 = getVariable("10102","0");
CNT_10103 = getVariable("10103","0");




var statOutput=''


statOutput+='--------------------------------------------------------'+NL;
statOutput+='SUBSCRIBER COUNT (10100): '+ CNT_10100+NL;
statOutput+='SUBSCRIBER COUNT (10102): '+ CNT_10102+NL;
statOutput+='SUBSCRIBER COUNT (10103): '+ CNT_10103+NL;
statOutput+='--------------------------------------------------------'+NL;


The variable "statOutput" is send to next step to write it in a file.

I hope you have understood till this point.

The question here is, if there was an new status like 10104 or any other, then I need to update java script code.

Please, can you tell me how can this be done dynamically.
