*** CAUTION ***
The "FE" device is intended for use only
in software updating and development
procedures by knowledgeable people. Use

The "FE" device is used from the -11 to transfer files to and from the
TOPS-10 file system. Usually it is accessed through the use of -11
PIP, using device "FE:" as if it were a FILES-11 device.
Two file formats on the TOPS-10 file system are supported: 16-bit
binary files (in 18-bit bytes) and 7-bit ASCII files. The format of a
particular file is determined by the file mode and/or the file type.
If the file mode is 10(.IOIMG) the file is assumed to be in 16-bit
binary format. If the byte-size is neither 18 nor 7, the file type is
checked to determine the format. File types .ABS, .BIN, .EXB, .LDA,
.MCB, .OBJ, .OLB, .SML, .STB, .SYS, and .TSK are assumed to be 16-bit
binary format, all others are taken to be 7-bit ASCII files and the
proper swapping of bytes is performed during transfers.
RSX FORMAT FILE CONVERSION
Files used by the standard RSX tasks are required to be
record-formatted, while their counterparts on the TOPS-10 file system
do not. This applies to all ASCII text files (which must be in
formatted ASCII) and to formatted binary files, notably .EXB, .MCB,
.OBJ, .OLB, .SML, and .STB types. A program called "RSXT10" was
developed to do the necessary conversions, both to RSX format and back
to DOS/TOPS-10 format. RSXT10 prompts by typing "RSXT10>" to which
the user responds with the desired command. All commands to REST10
are described in RSXFMT.HLP, which can be invoked by the HELP command
The default conversion mode for the file is determined from the file
type and the first data word in the file. Note that RSX formatted
files and binary files are written in file mode 10(.IOIMG) to insure
binary transfer mode. Also note that all files read by KLDCP are not
read in record mode, and thereby do not require conversion. An
example of converting a group of files to RSX format:
RSXFMT>CONVERT DEV:[P,PN]INPUT.FIL DEV:[P,PN]OUTPUT.FIL

GETTING THE SYSTEM STARTED
The program "FE" must be running on the TOPS-10 system. If it is not
already running, it can be started by typing the following under [1,2]
(probably under OPSER):
The "FE" program should now be running and is waiting for a request
from the "FE" device from the -11. The next step is to mount the "FE"
device from the -11 such that files can be accessed using it. This
requires that the file "T20ACP.TSK" be present on the -11 file system.
"FE" can be mounted using the Consol Command Parser at the console
terminal by typing:
MOU -- MOUNT COMPLETE
ADDRESSING TOPS-10 FILES
All files on the TOPS-10 file system may be accessed from the -11.
The FE program reads a file called FEUIC.TXT when it is started which
determines the mapping from TOPS-10 directories to UIC's on the -11.
The format of each line of this file is as follows:
[grp,usr] is the UIC on the -11.
str: is a file structure name, or "DSK:" for the search list for the
job running the FE program. If this field is absent, all
structures will be searched.
[p,pn,sfd1,sfd2...] is the TOPS-10 directory name.
FEUIC.TXT may exist on DSK: or SYS:.
Files are merely referenced by file name. Note that generation
numbers on the -11 are in octal, and are punctuated by a ";".
USING -11 PIP
-11 PIP is used in almost all transfers through the "FE" device. PIP
can be requested through the Console Command Language using the "MCR
PIP" command. The following basic commands can be used to list and
Guide to Using the "FE" Device Page 4
To list a TOPS-10 directory on device DEV:
PIP>dev:FE:[uic]file.typ;nnn/LI (or /BR or /FU)
To copy a file to the -11 file system:
To copy a file from the -11 file system:
To delete a file:
dev- is an -11 device which is mounted. If absent, SY: the (system
device) is assumed for files, TT: (the control terminal) for
directory listings. [uic] is optional and defaults to [5,5]. /NV
(New Version) is recommended in transferring files. To exit from PIP,
type ^Z (Control-Z).

TERMINATION OF "FE" DEVICE
When all the desired files have been transferred, the "FE" device
should be dismounted to free up system resources in use. Dismounting
the "FE" device is done by typing at the console terminal:
DMO -- DISMOUNT COMPLETE
