Matthias Boehm commented on SYSTEMML-535:
-----------------------------------------

This is a very useful feature that come up many times. However, I would recommend to overload our existing print function w/ multiple arguments similar to printf.

> Currently it is difficult to format console output in DML/PyDML. A printf built-in function would be useful for formatting console output. Matrix data by its nature is tabular, and a printf function (such as in C, Java, etc) is a convenient way to align results into readable columns.
