Foreign Command
A foreign command is a symbol that represents the file specification of a non-DCL image and can be used to invoke that image. The dollar sign in front of the file specification is required since it implies a RUN command.
$ PRINTALL :== $[ACCOUNTS]PRINTALL
For the image file specification, the default device and directory name is SYS$SYSTEM, the default file type is .EXE, and the default file version number is the highest version, so the foreign command above will run PRINTALL.EXE; located in SYS$SYSDEVICE:[ACCOUNTS].
