I am writing a menu driven Korn script where I am getting some input from the users (host details, like Hostname, HBA WWN, Devices etc...).

I made a screen within a screen.
Is there a way to move the inner screen up one level so that it is at the same level as the first screen running from the shell? (2 Replies)
On the NI-VISA boards there has been some frustration where folks cannot get NI-VISA to work on macOS Catalina because Catalina (macOS 10.15.x) is "not supported" by NI-VISA (for many months, it seems). Currently, the README shows:

scr_init
curs_scr_dump(3CURSES) Curses Library Functions curs_scr_dump(3CURSES)NAME
curs_scr_dump, scr_dump, scr_restore, scr_init, scr_set - read or write a curses screen from or to a file
SYNOPSIS
cc [ flag ... ] file ... -lcurses [ library ... ]
#include <curses.h>
int scr_dump(char *filename);
int scr_restore(char *filename);
int scr_init(char *filename);
int scr_set(char *filename);
DESCRIPTION
With the scr_dump() routine, the current contents of the virtual screen are written to the file filename.
With the scr_restore() routine, the virtual screen is set to the contents of filename, which must have been written using scr_dump(). The
next call to doupdate() restores the screen to the way it looked in the dump file.
With the scr_init() routine, the contents of filename are read in and used to initialize the curses data structures about what the terminal
currently has on its screen. If the data is determined to be valid, curses bases its next update of the screen on this information rather
than clearing the screen and starting from scratch. scr_init() is used after initscr() or a system(3C) call to share the screen with
another process which has done a scr_dump() after its endwin() call. The data is declared invalid if the time-stamp of the tty is old or
the terminfo capabilities rmcup() and nrrmc() exist.
The scr_set() routine is a combination of scr_restore() and scr_init(). It tells the program that the information in filename is what is
currently on the screen, and also what the program wants on the screen. This can be thought of as a screen inheritance function.
To read (write) a window from (to) a file, use the getwin() and putwin() routines (see curs_util(3CURSES)).
RETURN VALUES
All routines return the integer ERR upon failure and OK upon success.
