PERFORMING DOWNLOADS
Use of RAM and Flash Memory
VX 520 R
EFERENCE GUIDE 107
If you do not insert a SETDRIVE.F special file in the download list, all files
download by default into the RAM (Drive I:) of the target file group. You can also
insert a zero-length file with the name SETDRIVE.I into the download list at any
point to indicate that all following files will download into RAM.
For example, the following batch download list loads the executable code file
FOO.OUT into the RAM of the selected file group (default Group 1). Because the
signature file, FOO.P7S is included, FOO.OUT is also authenticated when the
terminal restarts after the download.
The *GO variable in this example indicates that the FOO.OUT application executes
on restart, after successful authentication. The two data files that follow the zero-
length SETDRIVE.F file, FOO.DAT and FOO.VFT, are redirected into GID1 flash.
Because it follows the inserted zero-length SETDRIVE.I file, GOO.DAT
downloads into Group 1 RAM.

You can also insert zero-length SETGROUP.n files into a batch download list to
redirect files from the target file group to other file groups (see Redirecting Files to
Other File Groups). Together, the zero-length SETDRIVE.x and SETGROUP.n
files allow you flexibility to store files as required in the RAM or flash file systems,
and in specific file groups in a single batch download operation.
Redirecting Files to
Other File Groups
GID1 is the default terminal manager setting for performing downloads. Using the
terminal manager menu options, you can select another file group (GID 2–15) as
the target group for the application download. If you select another group, files
download directly into the RAM of that file group.
To redirect files from the selected target file group to another file group as part of
the download operation, insert a zero-length SETGROUP.n file in the batch
download list (the same as SETDRIVE.x). The syntax of this convention is
SETGROUP.n, where n = 1–15 for GIDs 1–15.
To create a zero-length SETGROUP file on the download computer, use the DOS
command REM as in the following example:
REM >SETGROUP.2
NOTE
You can only use zero-length SETDRIVE.x files for batch application downloads,
either direct or by telephone, and only using the DMM download tool (and not
DDL.EXE).
You cannot use this special file convention for operating system downloads or for
back-to-back application downloads.
