TechTip: C# for RPGers: Not All Strings Are Born Equal

This time around, I’ll explain a very important object-oriented (OO) concept and some neat things you can do with a string in C# using a new type of object: StringBuilder.

rafael victoria preiraWritten by Rafael Victória-Pereira

If you haven’t read the last couple of TechTips, here’s what I’ve talked about: I introduced strings as a slightly different data type (a complex one, when compared to the simple data type presented before) and showed how to extract characters from it using a method called “substring.” Substring is very similar to an RPG BIF, but it’s a part of the string object, not a standalone function. Strings are objects and have “internal BIFs,” called “methods.” Some are similar to the RPG BIFs you know; others are something totally different.

TechTip: DB2 11 for z/OS Performance and Tuning Tips

Raise or lower the priority of a workload as needed to meet user-specified goals.

susan lawsonWritten by Susan Lawson

This article is an excerpt from chapter 6, “Performance and Tuning,” of DB2 11 for z/OS Database Administration: Certification Study Guide (Exam 312).


Using z/OS Workload Manager (WLM), you can set z/OS performance options for DB2. With WLM, you define performance goals and assign a business importance to each goal. The goals for work are defined in business terms, and the system decides how much resource, such as CPU and storage, to give to the work to meet its goal.


WLM controls the dispatching priority based on the user-supplied goals. It raises or lowers the priority as needed to meet the specified goal. Thus, you need not fine-tune the exact priorities of every piece of work in the system and can focus instead on business objectives.

MC SCBG Featured Product

TLAForms by TL Ashford converts your traditional IBM i spool files into high quality, professional forms.

Use a GUI Designer to create forms using data from a spool file and data from your IBM i files. Forms can be designed with true-type fonts, bar codes – including QR Code and Datamatrix, color images, overlays, lines, boxes and ellipses all in full color.

The software generates your forms as PDF documents that are archived to the IFS, automatically emailed and/or printed. Forms can be printed to IBM i PostScript printers, any printer connected to the network, or any printer connected to a PC. IFS locations, email addresses, and printers can be variable based on data within the spool file, data within the IBM i file or spool file attributes.

No programming is required to generate the new forms from your existing ERP, WMS or in-house application software.

The experienced TL Ashford technical support team will provide any pre-designed templates like the VICS Bill of Lading, and make sure working with the software is as easy and productive as possible!
