When I work at a client's location, I am often restricted to only one display device. If I am editing a source member and realize I forgot to create a printer file, for example, my choices for creating the new member are limited: I can exit the source member I am currently working on and start a new edit session for the new member, I can press the F21 key to get a command line and start SEU or PDM, or I can use the System Request menu to start a second display session and start SEU from there.
No matter which way I go, it's easy to get distracted and forget where I was in the first edit session while I'm taking care of the problem in the second. When I am exceptionally busy, I sometimes forget I even had a previous SEU edit session going and attempt to start SEU on the same member I am already editing.
To avoid this problem, I created the Edit Source (EDTSRC) utility. It allows me to run multiple SEU sessions from a command line. As I am editing one member, I can press the F21 key to get a command line, run this utility, and start editing a second member. When I exit the second member, my session resumes at the command line activated in the first member.
The EDTSRC command (Figure 9) prompts for the name of a source file, the library, the source member, the member type, and an SEU option. This utility lets me edit, browse, or print a source member. EDTSRC's command processing program (CPP), EDT01C, is shown in Figure 10.
If the member name I enter does not exist in the source file, a new member is added to the source file, and SEU starts with a blank member. If the member name I enter is already in use, SEU starts in BROWSE mode.
When I exit the SEU session, the Create Object (CRTOBJ) command is called. Source code for CRTOBJ and its CPP, CRT01C, is in Figures 11 and 12.
The relevant source file, library, and member name are passed to CRTOBJ, and I am prompted to create the object. If I specify *NO on the create parameter, control returns to EDTSRC and
then back to the original edit session. If I specify *YES on the create parameter, the appropriate CRTOBJ command, based on the source member type, is executed and sent to batch.
I added only the most commonly used CRTOBJ commands to this utility. You can easily expand this utility if you need to create other object types, such as panel groups.
Both CL programs use the Forward Program Message (FWDPGMMSG) utility, which was presented in "How to Forward Messages in CL," MC, January 1998.

Automate your backups with the Robot Backup and Recovery Solution. Key features include:
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:
