Synopsis
D f[,nnn]
Arguments
| f | A field number in the input buffer, specifying which field to display. If f=0, display the entire input buffer. f can be specified as an integer, or as a reference to a buffer or a select list that contains the integer. |
| nnn | Optional — An integer specifying the number of characters in f to display, starting from the current position.
