Columns()
columns(<list>, <width>[, <delim>[, <indent>]])
Formats a delimited <list> into fixed-width columns. Any element longer than <width> is truncated. <indent> specifies a left margin.
This function fits the margin and as many columns as possible into a 78-wide screen.
The input delimiter, <delim>, defaults to a space.
The left margin width, <indent>, defaults to zero.
