Hello Ken

I've read printf FORMAT LIST and edited your program to learn how it behaves; however, I do not understand it completely, can you explain some things I am still doubtful?

So, I edited your $fmt statement and tried to left-adjust and play with the spaces in between columns; however, I cannot understand the spaces between the 3rd and 4th columns.

 my $fmt = "%-13s % 24f %-24f %-4s\n %38.6f %14f %-4s\n";

the output of some of the 2nd columns seems to be left-justified except when the number is negative. How can that negative be moved in one more space so everything is left-justified?

And, the spacing between the 3rd and 4th columns are not clear to me yet? I know that Between the % and the format letter, some attributes control the interpretation, Can you explain how these spaces are moved in the 3rd and 4th fields?

I'll like to see all columns left-justified (the negative number is also left-justified with the number below or above) and little bigger spaces in between. Note, that there can only be 6 decimal numbers in columns and upto 13-character string name is allowed.
