Setting up the display unit

The SCODB vi mode uses display unit strings which must be set. The purpose of the strings is evident from the name of the string variables.

SCODB as released only supports ANSI console displays and Wyse 60 terminals. To support a different terminal, modify the appropriate items in the /etc/conf/pack.d/scodb/scodb_tty.i file.

SCODB does not verify correctness of display unit settings, so use great care in modifying any settings, and keep a backup copy of any files changed.

The strings, along with their default values (for ANSI displays and Wyse 60 terminals), TERMINFO, and TERMCAP names are:

number of lines per screen

The scodb_nlines variable defines the number of lines that can be displayed on the screen:

   int	scodb_nlines = 25;	/* lines on screen */

This value may be found by consulting the terminfo or termcap entry for the given terminal; the terminfo name is lines and the termcap name is li.

current row and column

The scodb_row and scodb_col variables enable SCODB to know where on the screen the cursor is:

   int scodb_row() { }
   int scodb_col() { }
