For example you might want to split this run-time dialog

%AskBox=Roughing-Feed=Roughing-Feed=Roughing-Spindle-Speed=Roughing-Spindle-Speed=First-Pass-Z-Offset=First-Pass-Z-Offset=Second-Pass-Z-Offset=Second-Pass-Z-Offset

into these two separate ones

%AskBox=Roughing-Feed=Roughing-Feed=Roughing-Spindle-Speed=Roughing-Spindle-Speed

%AskBox=First-Pass-Z-Offset=First-Pass-Z-Offset=Second-Pass-Z-Offset=Second-Pass-Z-Offset

Note that variables appear to be listed twice. This is because the prompt text is taken from the variable name. Each pair represents Prompt Text=Variable name. If required, further edits can be made to change the prompt text, but not the variable names.
