Many moons ago in the AutoCAD world, when you received a command prompt instead of an expected dialog box, you could check the system variables FILEDIA and CMDDIA and make sure they were set to 1. Over the years, CMDDIA has all but been phased out in AutoCAD, although FILEDIA (for FILE DIAlogs) does still apply. Here is a related post on this.
In AutoCAD MAP (and for MAP commands in Civil 3D) however, CMDDIA does still have an effect on many commands. If you run a MAP command and do not get an expected dialog box, check to make sure CMDDIA = 1. This includes command such as MAPCSCREATE, ADEDEFDATA, ADEQUERY, etc. Some other MAP commands such as MAPCLEAN, do not honor this variable and will always display the dialog box.
