*All* IBM i shops have legacy RPG applications. These applications are typically built out of hundreds, sometimes thousands, of RPG programs. It's not uncommon for many of those RPG programs to be reusable program objects that are called by many other RPG programs in the application. This article shows how to use ASNA Visual RPG's Call/Parm to call IBM i program objects.
The seven-digit date (in the format cyymmdd) is used in some IBM i ERP and custom applications. This article shows how to use that date type with ASNA Visual RPG.
When reading from a record format in a physical or logical file it is often handy to map fields from that format to array elements. This article shows you how.
You can easily pass an AVR for .NET array, as an argument, to subroutines and functions. This article explains how and reveals a "gotcha"!
Arrays in AVR are instances of .NET's System.Array class. This article explains some of the ways you can use AVR for .NET array methods and properties.
AVR for .NET's dynamically-sized ranked arrays let array element sizes be determined at runtime. This article explains how to use ranked arrays.
Storing data in arrays is a key way to implement effective and efficient algorithms. This article series takes a look at the different ways you can use arrays in AVR for .NET. This article explains AVR for .NET array basics.
The MemoryFile is one of ASNA Visual RPG's (AVR) most frequently used objects. The MemoryFile is a programming interface that wraps .NET's System.Data.DataSet. It allows rows to be written to an underlying DataTable with the RPG Write operation. This article discusses the two ways to define a MemoryFile.
This article provides a quick tip on how to convert an AVR for .NET date data type to a numeric value.
