The IBM i operating system includes hundreds of commands that we use every day. Everything you type on a command line is a command! But did you know that you can create commands of your very own? Commands that can save you valuable time? Commands that can be used as building blocks to make program development more efficient? Come to this session to learn how - and to have some fun! We'll start with the basics for those who've never created a command, and then proceed through more advanced topics such as validation using DEP & QUAL, error handling, help text in panel groups, and more. We'll look at a number of useful examples of custom commands, and you'll even leave with free source code you can use as is, or leverage as a starting point for your own commands. We'll reinforce the concepts we learn by playing Command Jeopardy... for prizes! Learn some great techniques, have some fun, and maybe leave with a prize!
