Lines from the code:

Var.Variance = row6.Sum - row4.Diff;// # # # # # # # # # # # # # # # # # # # # # # # # # # # # # # #

tFileInputDelimited_4Process(globalMap);

int exitCode = pcrfvspgwsmalldataClass.runJobInTOS(args);

The tmap function is doing a join between two data sets and difference between values of two columns
