The WRITE (abbreviated WR) command creates a file from a specified range
 of lines.

 Format: WRITE file-spec [range] [/SEQUENCE[:init:incr]]

 When you specify a range, the text contained in that range becomes the
 file. When you do not specify a range, the contents of the current text
 buffer becomes the new file.  The cursor position is not affected by the
 WRITE command.
