I have written hundreds of Local Minitab Macros with numerous subcommands.
Normally these are launched using the Command Line Editor, using the % sign to indicate the macro filename, see Figure 1 to the right.
As you can see it might be a bit confusing to remember what all parameter settings are supposed to be.
That's why I write Dialog Boxes that launch right in Minitab itself, so that the parameters are all clearly identified, see Figure 2 at right which is the dialog box that creates the code in Figure 1. See figure 3 & 4 for additional examples of Enhanced Minitab Macros I have written for clients.
