WW / WW
The number of lines to be swapped. If you do not type a number, or if the number you type is 1, only the line on which you type W is swapped. For the WW command, the n operand cannot be used.
The W/WW line command is used to mark off one or more lines which are swapped with one or more lines marked with M or MM. W and WW are only valid for swapping lines between an M/MM block, and cannot be used for any other purpose.
See the description of M/MM for more information.
Note: See Word Processing Support for information about text swaps.
Example of using M/MM and W/WW to swap lines:
