The number of API’s available on the Power i are increasing with each release of the OS. Why aren’t you taking advantage of these handy tools?

Binding Directories

Posted by MrPort in Binding Directories | Comments off

Did you know by placing the correct H spec in your RPG code listing a binding directory you can eliminate the need to manually bind all procedures and service programs when you create your program?

The use of binding directories in combination with /Copy code can help standardize your applications and reduce complex processes to compile code.

Service Programs

When do you use a service program and when do you use a module? There is a difference in performance with each and using the correct method can save processing time for your applications. We use modules when they are called for and service programs when the application justifies it.

As always, if you have questions we’d love to help you answer them.

Embedded SQL

Posted by MrPort in Embedded SQL | Comments off

Have you wanted to see multiple views of a physical file and had to create a logical file for each view? How about deleting whole sets of records without chaining or reading each one?

With embedded SQL in RPG we can gather data from files in almost any view without creating logical files. The flexibility this provides is nearly invaluable. We can incorporate embedded SQL in applications for you.

Contact us for a sample embedded SQL RPGLE program.
