LINELENGTH _ _ _ _ _ _ _ _ _ _ _ _ declaration
The linelength declaration sets the length of the output line. Default is 80.
linelength<expression>
To change the linelength, <expression> must evaluate to a positive integer less than 128 (although this varies from system to system), and should not be less than 20 or so for proper operation.
linelengthreturns the previous linelength. If you want the current linelength value, but not change it, say linelength nil.
