You can pass them with a separator and within your processor stage you can use them accordingly. Or if A123, B456, 0C56 values are part of a record and you want to send these as a parameter by Start Jobs processor then you can use code or Expression evaluator to create a single string and then pass this to the called Job.

Hi @Bikram 

can you please suggest an approach for reading the same data1 variable (having multiple values, separated by comma) by using expression evaluator.

I need to verify, whether the input record flowing from source contains any one of the data present in data1 variable.

@Priyabala 

Here is a way to do this

Dev Data Source has a field called f1 with a value of ‘abc’

I have created a parameter called data1 with value 0000;abc;1234;defg;3244;2222

Use Expression evaluator to split the parameter to a list of values

Add Javascriot evaluator and following code

var matchFound = false;
for (var j = 0; j < recordsli].value.split.length; j++) {
  if (recordsii].value.splitvj] === records=i].value.f1) {
    matchFound = true;
    break;
  }
}

The output looks like this

If i change the parameter to 0000;abcd;1234;defg;3244;2222. I get false

I hope it helps.
