I found a program for managing the client to connect to job 400 on the Internet.

There are many features.
ProgramReadability is good, and many program styles are worth learning.
The most interesting thing is the program remarks. What colors are available, white and red flashing, dazzling .....

Then, IP filtering is added based on your needs.

====================
This is a recommended savf upload method.
The file in the zip is a AS/400 save file. I like to do it like this:
-Unzip the file into a directory on the PC
-Start a DOS prompt in that directory
-Start a FTP session to your 400
-Then log into the FTP server
-From the ftp> prompt
Ftp> Cd qgpl
Ftp> Bin
Ftp> quote site namefmt 1
Ftp> put savefilename. savf
Ftp> quit

Then from the 400 command line
Rstobj * All qtemp * savf
Savf (qgpl/savefilename)
Rstlib (your_favorite_library)
======================================
