  The Very Large Tele­scope (VLT) pro­ject of ESO con­sists of an array of four op­ti­cal tele­scopes of 8 m di­am­e­ter, to be in­stalled at a new site in the At­a­cama desert in Chile start­ing in 1995. The con­trol soft­ware is com­pletely dis­trib­uted, being based on LANs in­ter­con­nect­ing mi­cro­proces­sors and work­stations, where sev­eral users and op­er­a­tors will be ac­tive at the same time. Mi­cro­proces­sors are used in a va­ri­ety of con­trol func­tions, in­clud­ing the ac­tive con­trol of the shape of the main mir­ror and com­pen­sa­tion for at­mos­pheric tur­bu­lence. Ded­i­cated links and an­ten­nas are planned for di­rect com­munication and re­mote ob­ser­va­tion from var­i­ous Eu­ro­pean cen­ters. The main con­cepts and nov­el­ties of the soft­ware de­sign are ex­plained.
