XRDB This program is used to display/modify the RESOURCE_MANAGER property on the root window. Most users will probably never need it, but it is interesting to see what DECwindows sets up. You can achieve the same effects by creating a DECW$XDEFAULTS.DAT file in your login area, although this requires you to quit the session for the new values to take effect. You can obtain the same information using XPROP on the root window. However, XRDB formats the data so that it is easier to read. There is no C preprocessor under VMS, so this option should be ignored. This also results in one undefined external, popen(). However, as it should never be called, this is not worth worrying about.
