108 VX 520 REFERENCE GUIDE
If you do not insert SETGROUP.n special files into the download list, all files
download into the target group selected in terminal manager. If no number is
added to the SETGROUP filename, SETGROUP.1 (GID1) is assumed.
Restrictions on File
Redirection
The VX 520 file system restricts how you can redirect files to other file groups.
Here are the important points to remember:
• The main application must always be downloaded into GID1.
• Because of the way file groups are managed in the VX 520 file system, only
two schemes are available for redirecting files during a batch application
download:
• If using terminal manager menu options, select Group 1 (default) as the
target group for the download; files can be redirected to any other file
group, including GID15.
• If using terminal manager menu options, select a file group other than
Group 1 (GIDs 2–14) as the target group for the download; files can be
redirected only into the selected file group or into GID15.
In the following example, GID1 is selected as the target group for the download.
The download list loads FOO.OUT into Group 1 RAM, GOO.OUT into GID2, and
COMN.LIB shared library into GID15. When the terminal restarts after the
download, the file authentication module is invoked for all three files, based on the
certificate data that authorizes them to be stored in their respective file groups.
If FOO.OUT is authenticated, the GID1 application, FOO.OUT, executes as
specified by the *GO variable when the terminal restarts following successful file
authentication. The function library stored in GID15 can be shared by both
applications, as both Group 1 and Group 2 applications can access Group 15.

NOTE
You can only use zero-length SETGROUP.x files for batch application downloads,
either direct or telephone, and only using the Download Manager or ZonTalk
2000 download tools (not DDL.EXE). You cannot use this special file convention
for operating system downloads or back-to-back application downloads.
