Editing Capabilities

The following termcap functions are used for editing functions:

Name	Description
cl=str	Clear screen
cd=str	Clear to end of display
ce=str	Clear to end of line
dl=str	Delete line
al=str	Insert line
dc=str	Delete character
ic=str	Insert character
im=str	Start insert mode
ei=str	End insert mode

If the cd capability is not defined, PRO/5 will simulate it with a series of ce's, except in the case of a cd at the home position where a cl may be used.

If the insert line or delete line capabilities are missing, PRO/5 will attempt to emulate them by a refreshing the affected region on the screen. If a terminal is operating at a low baud rate or requires considerable delay padding, the display performance may be slow. This is particularly noticeable when attempting to scroll within a large window.

If ic is not found, PRO/5 will attempt to use im and ei pairs with spaces (insert mode on, space, insert mode off). This may be slower than a terminal using the ic capability. If neither insert nor delete character capabilities can be found, PRO/5 will emulate their functions by refreshing the affected region with the proper characters and attributes.
