Filer6 requires at least ROM 1.23 for the 49G+.
For a 49G+ or 49G with an older ROM version use one of the filers of the Filers
package. Main advantages over the standard filer are:
- Entering first the scanned directory, not the
TREE which is on
(backspace).
- No search in the menu anymore. Suitable hardkeys keep the menu
small. Option KEYS provides a crib sheet to
the hardkey functions seen in the first screen-shot below.
- There are several new options, e.g., a VERSION and CAS summary on key
V and a powerful option on key SPC for hiding, archiving and
restoring. Further options can be activated via APPS.
- ENTER leaves the filer and enters the currently scanned directory;
multi-selecting
is done with the
+/- key.
- The use of shifted keys has been minimized. Besides ALPHA-shifting for name search, there are
only 2 shiftings.
These shiftings are RS N (CHARS) for name sorting (because unshifted N
has become EVAL on the 49+) and LS 2 (DEF)
for defining or creating a new directory or file.
This option is much more powerful
than NEW in the standard filer. Clearly, it errors in a standard port because
it saves only backups or libraries. But it allows the creation of directories
or files also on the SD-card from inside port3 or any of its
subdirectories as shown in the screen-shot. This dialog box was
launched after passing to the card to create the subdirectory SOURCE for
downloading HP source files (as a rule ordinary text files). Hence, the
Directory option is checked. When crreating a directory the black Object:
field should be skipped. If pressing OK you'll see the subdirectory SOURCE,
either in the card root or in the currently scanned card directly. The new
directory is not empty but contains a dummy named # (sharp), with the system
binary # FFFFFh in it. This fixes a bug in operating system which doesn't
allow the creation of files inside an empty card directory. After storing a
useful file in SOURCE you may purge '#'.
To purge a card directory is presently only possible with a card reader.
Note that some other hardcoded shiftings, e.g. leftshift N, are basically redundant since key I toggles Inversion
for any kind of sorting.
What is New?
Version 5.2004: Simplified Find option on the ALPHA key known from
Filer2 returned. NEW on RS DEF improved.
Version 4.2004: Key DEF (RS 2) makes option NEW more powerful.
Creates directories or files also directly on the card.
Version 3.2004: Simplified. Document reading removed. This is
realized by Headman. Clock toggling unshifted on key 9.
First Version released February 2004 -
Abbreviations: LS = LeftShift, RS = RightShift .
All other options are on hard keys.
The menu option KEYS informs
on active
keys during a filers run as shown by the screen-shot.
Active hard keys are listed in more detail below and referred to by the letter on it -
provided there is any. After a while, you'll remember the relevant keys.
The other options from page 1 are self-explaining. PURGE is executed with or without confirmation,
depending on flag -76. Like COPY, PURGE and RCL, it may be used with multi-selection.
Selection is done with the +/- key. EDITB ("Edit Best") edits like
, while LS EDITB edits an object always in a command
line like LS
. For
instance, pressing EDITB on PERIOD in the CAS menu, you see 2pi
in the equation writer, but pressing LS EDITB you see '2*pi'
in the edit line. In addition, there is a SysRPL editor on RS
EDITB, displaying PERIOD as "SYMBOL ZINT 2 xPI x*".
This function should only be used by those familiar with the
basics of SysRPL. Note that COPY and MOVE overwrite an equally named backup
when
copying from a directory to a port.
IOP is a very comfortable I/O parameter setter. It sets a
screen and menu for toggling
wire/infrared and ascii/binary and cycling through all
admissible IOPAR values relevant for the 49+.
CANCEL
and OK leave the IOP box and set the currently displayed values which the
user might have changed. You may reset all values to their default with Reset
on the 2nd menu page. Remember that the reserved variable IOPAR does not include any setting of wire/infrared
or ascii/binary! ~OVW toggles the Overwrite flag. The transfer options SEND, RECV and XSEND can be used
with multiple choice. For more details read
Ioman.htm
SD
copies the selected files
to the SD-card provided you are in a standard port. If a library was selected
or belongs to the selections, a directory LIBS is created
on the card in which the library is stored, to keep the card's file
structure easy to survey. If on the card, SD copies the selected files to the port
choosen in a special port choose dialog. If being in HOME or another directory, SD
may still do something different because from a directory can be copied to the card with COPY. Hence, in this case SD
saves all standard ports on the card in one keystroke. This amazing function allows returning a
defective unit to the dealer and keeping all data on a card,
including all libraries! HOME backups with long
names are not transfered to the card since dated HOME backups
can directly be created on the card very easily with the SPC key. Note that
(empty) directories and files can also directly be created with the
DEF key (LS 2). You cannot create something in an empty card directory,
neither with the standard filer nor with Filer6 (a bug in the operating
system). You've first to copy something to make the directory non-empty. Attention:
In contrast to COPY or MOVE, SD
never overwrites. If two objects have the same backup name in different
standard ports, only the
one with smaller port number is saved on the card. This concerns in
particular
distinct versions of the same library.
Arrow keys work as in the built-in filer. For
instance,
goes UPDIR,
to a selected
directory. Use key U to see in the header were you are. Most hardkey options are active only if the main
appl menu is present, TREE has its own menu. More options can
be added to the APPS box. But these must not affect
the filers application menu. For instance, from APPS you may directly run the
Constants lib and I/O-functions inside a filer. Trivially valid hardkeys
in the filers
are not listed below (e.g. CANCEL, TurnOff). Keys working both
with a single item and multiple items are marked with an asterisk.
Hard Keys in Filer6
| G |
APPS choose box (for calling additonal
options inside the filers). |
| H |
Toggle two distinct Header views of
the filer. |
| I |
Toggle inverse sorting provided a
sorting (Name, Size, Type) is active. |
| J |
(VAR) Toggle complete view of variables or long
library titles if in a port. |
| K |
(STO) store the level 1 object in the selected name
by overwriting it. If in a
port, the level 1 object is stored in the current
directory under a corresponding name. The backup object itself
is not overwritten. |
| M * |
Move file to another directory or to
a port. Backups in ports will be
overwritten. |
| N |
Does EVAL. Name sorting is on
RS N. |
| O * |
Order a set of selected files
in a directory. |
| P |
Pause (HALT). Return to the filer
with CONT. The HLT indicator remains (bug) but disappears
with U. |
| |
Enters the TREE from anywhere. In ports or in HOME
the TREE is also set with
. |
| Q |
Quote the selected name. Quoting
in ports includes port-tag. Quoting in a subdirectory on the card
includes the path as a string. Only this is a valid argument for
EVAL and RCL and usable in programs. |
| R |
Rename. Beeps in a port since libraries and backups cannot be renamed. |
| S |
Size sorting of files. |
| T |
Type sorting of files. |
| U |
Unsort, original order
after any sorting. Removes also selection marks and updates
the header (clock etc). |
| V |
Version information as displayed in
this screen. Here V was pressed while visiting the card. The
screen-shot shows by the way how a HOME backup looks like if made on
the card with the SPC key, see below. Right after the backup symbol
you see the date of creation. |
| W (+/-) |
Multi-selection. Select and go to the next or
the
previous item. |
| ALPHA |
Find a file name after waiting for
its first letter in ALPHA mode after pressing ALPHA (no double-click
as in the standard filer). Case-insensitive search.
For names starting with $ or other special
symbols LS has to be used to obtain the character. When searching
for all names starting with N or n, say, simply toggle the left-hand thumb
on ALPHA with the right-hand thumb on N. |
| •
(dot) |
Immediate return to HOME from
anywhere, also from subdirectories of HOME (doesn't work in
standard filer). |
| 0,1,2,3 |
Immediate entry into ports 0, 1, 2 or 3 (SD-card) from anywhere.
|
| 9 |
Toggles clock display. Can be actualized with key U |
| SPC |
 Works
differently depending on whether in a directory or
a port. In a directory (including HOME), a choose box is launched as
shown in the screen shot. HIDE hides the selected files(s)
in the current directory. It creates a nullnamed file
displayed in the filer as
''...''´´
CHAR 3
which separates visibles from hiddens by putting the
latter behind the nullname ´´. Hidden files work normally and are invisible only in the VAR menu,
hence are well protected against overwriting. UNHIDE unhides the
selected files by putting them on top of the
directory. Clearly, if nothing is selected, just the scanned
name will be hidden or unhidden. ´´ contains a small dummy (character
H by default) but anything can be stored in
it with the filer's STO function. Also the so-called
Hidden directory has a nullname but this one is unvisible in all filers.
 When pressing SPC in port (including
the SD-card), a choose box as seen in
the example screen is set. ARCHIVE archives the entire HOME
directory including key assignments in the scanned port, with date and time
appended (on the card only date).
Date format depends on flag -42.
Key VAR uncovers the time of creation. Home backups or libraries
should only temporarily stored in port0. Since the card does not accept long names, a HOME
backup on the card displays only the date while a HOME backup in a standard port
looks as in the screen, containing date&time of creation. For restoring, we
suggest first pressing key T. This puts all candidates for RESTORE closely together. Then
select the
desired HOME backup and press RESTORE. In port2 or on the card
there is enough room for several HOME backups. |
| ENTER |
Enter the selected directory and
leave the filer. Equivalent to running CHDIR at the
end of the built-in filer menu and then leaving with
CANCEL. |
HINT for newbees. We recommend storing Filer6 in port2 and attaching it to a key. For instance, to LS APPS, so that switching USR mode toggles the selected Filer
with the built-in filer. If you don't have libs in the ports or a
few, COPY may save them on the card. But if many libs are used, they are
better saved with SD
to keep the card easy to survey.
HINT for advanced users: The access to APPS makes
the filers more powerful. E.g., if the APPS box contains
BZDIR from OT49+, the scanned directory can be compressed as a
whole inside the filer. Keep a copy
of Filer6 in port2, for having access to it via the standard filer after a
crash - a filer invokes another one smoothly. RS EDITB applies ASM2
for recompilation. Hence, extable should exist and the
libraries 256 and 257 attached (which is granted provided OT49+ is present).
