The American Programmer

Here are the most useful manuals and tutorials on the IBM AS400 Midrange computer.
The IBM AS400 is an extremely powerful midrange computer. It has all the functionality of mainframes. With the OS400 operating system, it hosts server software, databases, mail servers.
It supports application development with CICS, COBOL, REXX, JAVA, C, C++, SQL, Fortran, and more.
Mastery of CL leads to mastery of the AS/400.
