[net.bugs] the Rand editor

johanw@ttds.UUCP (Johan Wide'n) (06/30/84)

Here is a bugfix for version 17 of the Rand editor (e17).

Index: e/e/term/tcap.c

Description: vt100-type scrolling of part of the screen is incorrectly
handled by tcap.c. The routine implementing the scrolling first sets
a scroll region. It then scrolls the screen (up or down). When it is finished
it should set the scroll region to the entire screen, this is not done.

Fix:
