The MODE command

The <MODE called with the parameter co#,# to set the window height and 
width  command accepts any combination of lines and columns as long as the 
the formula "lines x columns" does not exceed 8192. 

Example: 

 

mode co70,112

mode co160,51

You do not have to use the co, e.g 

 
mode co160,51

is the same as 

 
mode 160,51
