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.

1    /SEQUENCE

 Format: /SEQUENCE[:init:incr]

 When you use the /SEQUENCE option, the output file is in VFC (variable
 with fixed control) format, and line numbers are written in the control
 field. The values of both 'init' and 'incr' must be less than 65536.

 If you set init and incr, the file is renumbered starting with the number
 you choose for init, and the lines are incremented by the number you
 choose for incr.  Otherwise, the line numbers assigned by EDT are written.
 These line numbers are truncated to integers and taken modulo 100000,
 with a maximum value of 65535.
