Practical RPG: Data in the Cloud, Part 2

The cloud has successfully provided file storage since long before it was called the cloud, but does that success translate to databases?

joe plutaWritten by Joe Pluta

In my previous article, I introduced you to the concept of files in the cloud, whether it's a file-sharing service such as Dropbox or a whole-enterprise backup system using something like Carbonite or CrashPlan. But in this article, I want to focus on a relative newcomer to the playing field, databases in the cloud. These are true relational databases (RDBMSs)—or in the case of NoSQL, anti-RDBMSs in the sky. This article explains the difference between the two and introduces you to some of the players in today's market.

Can an ILE CL Program Know the Number of Parameters Passed to It?

Investigate the ILE CL compiler's mechanism for receiving program parameters.

junlei liWritten by Junlei Li

 

There's no doubt that the program-call mechanism in IBM i is fully dynamic. The called program can be determined at run time instead of at compile time. The parameter list passed to the called program can be composed at run time by the calling program. Also, the length of the parameter list for a called program can be changed dynamically. As you might know, an ILE RPG program can retrieve of the length of the parameter list via the RPG %PARMS built-in function (BIF). An ILE C program can also achieve this goal via the first argument of its main function, int argc. So is it possible for an ILE CL program to know the number of parameters passed to it? This article will lead you to answer, all the way down to the RISC instruction level.
