RightMargin (ne’s manual)

#### 4.8.6 RightMargin

Syntax: `RightMargin [n]`
Abbreviation: `RM`

sets the right margin for all formatting operations, and for `WordWrap`. See WordWrap.

If the optional argument n is not specified, you can enter it on the input line, the default being the current value of the right margin.

A value of zero for n will force `ne` to use (what it thinks it is) the current screen width as right margin.
