The .REPEAT command allows you to specify up to 150 characters
    to be printed a specified number of times, either horizontally or
    vertically. The text will be repeated horizontally when .FILL is
    in effect, and vertically when .NO FILL is in effect.

    Format

    Abreviated format

      .RPT  n "x" (or n 'x')
