What is AS/400 system?
Is there any difference in Z OS Cobol and Cobol for AS400 series?

[Robert Sample]

The AS/400 was introduced in 1988 as a minicomputer replacement for other IBM systems. AS/400 was renamed eServer iSeries in 2000, then system I in 2006 and continues to be sold. There are some differences between COBOL on z/OS and COBOL on system i, but as with all COBOL implementations the differences are typically related to the platform and accessing files. A READ statement on one platform will usually be the same as a READ statement on a different platform.

Thanks Sir. So all the syntax and coding standards are same for both systems? Means if a person has worked on Z-OS, can easily code for AS/400 systems aswell?

Yes. But why not look up the COBOL laguage reference manual for AS/400 or System I yourself?

Hello,

The CODE will be very similar.

The run-time environment will take some learning.
