DECSCPP—Select 80 or 132 Columns per Page

There are two control functions that can set the page width to 80 or 132 columns, DECSCPP and DECCOLM (DECCOLM—Select 80 or 132 Columns per Page).

Note

It is recommended that new applications use DECSCPP rather than DECCOLM. DECSCPP does not clear page memory or reset the scrolling regions as does DECCOLM. DECCOLM is provided mainly for compatibility with previous products.

Default: 80 columns

Notes on DECSCPP

DECSCPP changes the font to match the current number of columns on the page.
DECSCPP does not move the cursor. If, however, the cursor is beyond the width of the new page when DECSCPP executes, then the cursor moves to the right column of the new page.
If you switch from 132-column to 80-column pages, then you can lose data from page memory. Columns no longer present in page memory are lost. Make sure you set page columns before you enter data into page memory.
