# Terminal Features

Some terminals have more features than others. Refer to the following if you encounter problems when using your terminal.

Reverse Characters and Scrolling | On some terminals, pressing the reverse-mode key in "Define Screens" at position 1,1 causes the screen to scroll up by a few lines making it impossible to see the cursor and any reverse characters you may have typed. To correct the problem, re-display the screen by pressing the [redraw screen] key for your terminal.
Graphics | Some terminals do not have complete graphics capabilities. Although the graphics key turns on and off such terminals in "Define Screens", the characters accessed are plus signs (1-9), a dash(0) and a vertical line (the period) instead of the graphic bars and corners.
End Markers | End Markers on IBM terminals are small triangles. On other systems and terminals, the End Markers may be small boxes, periods or even question marks.
Lost Cursors | Some terminals don't have separate on and off sequences but use a toggle instead. On these terminals, it is possible for the cursor to disappear or get "lost". When this occurs, the [Restore Cursor] key turns the cursor back on.
