How IBM PASE for i programs interact with IBM i

As you customize your PASE for i programs to use IBM® i functions, you need to consider the ways in which your program will interact with them.

Communications
PASE for i is generally compatible with AIX® and Linux in sockets communications.
Database
PASE for i supports the Db2® for i call level interfaces (CLIs). DB2® CLIs on AIX and IBM i are not exact subsets of each other, so there are minor differences in a few interfaces. Some APIs in one implementation might not exist in another.
Data encoding
Most operating systems, such as AIX and Linux, use ASCII character encoding. Most IBM i functions use EBCDIC character encoding.
File systems
PASE for i programs can access any file or resource that is accessible through the integrated file system, including objects in the QSYS.LIB and QOPT file systems.
Globalization
Because the PASE for i run time is based on the AIX run time, PASE for i programs can use the same rich set of programming interfaces for locales, character string manipulation, date and time services, message catalogs, and character encoding conversions supported on AIX.
Message services
PASE for i signals and ILE signals are independent, so it is not possible to directly call a handler for one signal type by raising the other type of signal.
Printing output from IBM PASE for i applications
You can use the QShell Rfile utility to read and write output from PASE for i shells.
Pseudo-terminal (PTY)
PASE for i supports both AT&T and Berkeley Software Distributions (BSD) style devices. From a programming perspective, these devices work in PASE for i in the same way that they work on AIX.
Security
From a security point of view, PASE for i programs are subject to the same security restrictions as any other program on the IBM i operating system.
Work management
The IBM i operating system handles PASE for i programs in the same way it handles any other job on the system.
