Important Notice

The pages on this site contain documentation for very old MS-DOS software, purely for historical purposes. If you're looking for up-to-date documentation, particularly for programming, you should not rely on the information found here, as it will be woefully out of date.

     The <width> field contains a nonnegative decimal integer that
     specifies the minimum number of characters printed.
 
     If the number of characters in the output is less than the
     specified width, blanks are added to the left or the right of the
     output value (depending on whether the - flag is used) until the
     minimum width is reached. If <width> is prefixed with a 0, zeros
     are added until the minimum width is reached. (This is not useful
     for left-aligned numbers.)
 
     The width specification never causes a value to be truncated. If
     the number of characters in the output value is greater than the
     specified width, or <width> is not given, all characters of the
     value are printed (subject to the precision specification).
 
     If the width specification is an asterisk (*), the width is
     determined by the next argument, which must be an integer. The
     width argument must precede the value being formatted in the
     argument list.
