Desc resources store null-terminated text strings (descriptions) that are used by EV in a variety of places. For some desc resources, EV looks for a certain reserved ID number. Other desc resources are pointed to by fields in other resources, so their ID numbers are not necessarily fixed, and can be set to virtually anything by the scenario designer. The reserved desc ID numbers, along with the maximum length for each type, are below:
128-1628 Stellar object descriptions, shown when landed on a planet.
2000-2063 Ship class descriptions, shown in the shipyard and requisition-escort dialog.
2100-2163 Ship pilot descriptions, shown in the hire-escort dialog.
3000-3127 Outfit item descriptions, shown in ship outfitting dialog.
4000-4255 Mission descriptions, shown in mission dialog.
