Re: What to teach someone new to IBMi

Made a list of some general salient differences between *nix and IBM i for
a presentation some years ago.

Virtual machine since 1988

Machine code kernel

Record based

Stream based

Screen UI

Character stream UI

Externally coded navigators

X Windowing System

Proprietary

Open

Object-based and Role-based security

File-based security

5250 terminal

VT100 terminal

Development in workstation IDE

Development in native IDE

Batch oriented

Interactive oriented

Work management

Load management

EBCDIC

ASCII

Object File System OFS and Integrated File System IFS offer two different
yet parallel views of the system.

Various but similar hierarchical file systems.

IBM terminology often seemingly backwards from *NIX terminology

*NIX sometimes seemingly backwards , e.g., X Windowing System ”server” runs
on the client
