Q. I am in the middle of creating an interactive program that uses a subfile. The subfile provides input-capable fields on the leftmost column so the user can enter option numbers-like IBM's WRKSPLF command. In addition, I would like to provide several other input fields. Circumstances have forced me to include some of the additional input fields into a separate record format which is not the subfile control record. How can I code my RPG program so that it receives all input: the option numbers and the additional input fields?
A. All you need to do is code several READ operations one after the other. For example, let's suppose your subfile control record is called CTL1 and the other input-capable panel is called INPUT1. Code the following:
C WRITEINPUT1 C EXFMTCTL1 C READ INPUT1 99
The EXFMT operation on the subfile control record (CTL1) reads the subfile control record (if any input fields are present) and the option fields from the subfile records. The READ operation that follows processes the additional panel you have.
Business users want new applications now. Market and regulatory pressures require faster application updates and delivery into production. Your IBM i developers may be approaching retirement, and you see no sure way to fill their positions with experienced developers. In addition, you may be caught between maintaining your existing applications and the uncertainty of moving to something new.
IT managers hoping to find new IBM i talent are discovering that the pool of experienced RPG programmers and operators or administrators with intimate knowledge of the operating system and the applications that run on it is small. This begs the question: How will you manage the platform that supports such a big part of your business? This guide offers strategies and software suggestions to help you plan IT staffing and resources and smooth the transition after your AS/400 talent retires. Read on to learn:
