----------------------------------------

Whenever the ImportReadData.java class is used, opening file and closing file
happens several times. Therefore would it be a issue?

That's a very good point. I don't want to prematurely optimize.
Your proposed implementation is straightforward and clear.
Let's see how the testing goes; maybe you can look at some ways to try
to make sure that we exercise multiple-open code paths in our new tests
and we can see if we hit any problems or not.

> To ease maintainability and legibility of client programs, it would be
> nice if callers of SYSCS_IMPORT_DATA_BULK (and possibly also
> SYSCS_IMPORT_DATA) could refer to columns in the COLUMNINDEXES
> argument by column *NAME*, as well as by index *NUMBER*.
> So, for example, a valid COLUMNINDEXES specification might be:
> '1,3,LastName,FirstName,7'
