The following statements assign the specified files to the DISPlay unit:
SET DISPlay=USER1:[HOME.SUBDIRECTORY]TESTING_ABCDE.EXT;4 END SET DISPlay=/mnt/usr/users/home/sub/testing.test ENDOn all UNIX and VAX/VMS systems, X-PLOR provides the feature of environmental variables or logical definitions. Suppose the user has defined a UNIX variable TOPPAR in his ``.cshrc" file
setenv TOPPAR /user/topparThen it is possible to access a file ``xyz" in the directory ``/user/toppar" in X-PLOR by specifying the filename ``TOPPAR:xyz", e.g., if the user wants to set the DISPLay file,
SET DISPlay=TOPPAR:xyzThe same feature can be used on VAX/VMS systems by including a logical assignment statement in the user's login file:
$ ASSIGN/NOLOG user:[toppar] $TOPPAR
