Certain edit descriptors have been extended to allow formatted output of numeric values, while minimising the amount of "white space" produced. This extension permits more information to be presented on a limited width display device (e.g. terminal), without concern about overflowing a user specified field width. Allowing a zero field width to be specified for the I, B, 0, Z and F edit descriptors provides this functionality. A field width specification of zero always specifies a minimum field width; it never specifies suppression of data output or an actual field width of zero.
