An arrangement is disclosed which enables the variation of the working environment of a computer comprising a working memory, a central processor unit and a plurality of peripheral units including an external memory. The arrangement comprises a switch having a plurality of positions associated with respective working environments and a logic control device responsive to the switch to introduce a group of microprograms, programs forming the operative system and at least one application program associated with the selected position of the switch from the external memory into the working memory. The programs and microprograms introduced into the working memory then are used to control the peripheral units in such a manner to establish different groups of functions, each group specializing the computer for the selected environment.
