Each week, Lotus's Product Support receives thousands of phone calls about
1-2-3. Many of these questions are asked frequently. The following is a list of
the "Top Twenty" asked by Lotus dealers and Product Support's answers to these
frequent questions. We hope they will provide the timely and concise
information that you need.
Worksheet
Q: What is the internal precision of 1-2-3?
A: 1-2-3 has internal precision of 15 decimal places.
Q: Sometimes when I use functions that compare or evaluate
numbers, the comparison comes up false, even though the
numbers on the screen are equal. Why?
A: This happens because 1-2-3 stores all numbers internally to 15 decimal
places and rounds off only the displayed number. Thus 2.00 on the screen
could actually be 2.0001 internally; comparing this to 2.00 exactly will
come up false. The solution is to use the @ROUND function to round off
numbers to exact amounts -- especially important if the numbers are a result
of calculations using division, sine, cosine, square root, etc. which often
change the very last decimal place by one digit or so.
Q: I've followed your instructions exactly, but I still can't
get my hard disk to go past the Access System Menu.
A: The 1-2-3 System Disk is still copy protected. Therefore,
when you get to the Access System Menu, place the System Disk
in the floppy drive and press [Return].
Q: Please explain the benefits and limitations of
subdirectories. Release 1A documentation states "limited"
use of DOS 2.0 tree directories. What does this mean?
A: Subdirectories are created in DOS 2.0 by the MAKE DIRECTORY
command. Subdirectories allow better organization and the
ability to store a larger number of files on the hard disk.
Their limitation in 1-2-3 is that you can't use the DOS PATH
command to find files.
Q: When I design a large worksheet, the constant recalculation
slows me down considerably. Is there anything I can do to
speed things up?
A: Yes. Switch to manual recalculation and your problem will be
solved. The correct keystrokes are /WGRM. This will
suppress recalculation until the user presses [CALC].
Q: Does 1-2-3 support alpha character string functions?
A: No, it does not.
Q: When I attempt to retrieve a file, I get the error 'Range
Name Already Exists.'
A: This is caused by trying to retrieve, under Release 1, a
Release 1A- created file containing graph names. To solve
the problem, go back to Release 1A, delete the graph names
and resave the file. Then retrieve it under Release 1.
Q: Why is it that when retrieving a file, the number of bytes
free found when executing /WS does not decrement by the same
amount as the file? I checked the size in the FILE MANAGER
before retrieving it.
A: Due to additional overhead, the size of a file once brought
into RAM is larger than the size found when using the FILE
MANAGER or DOS DIR command.
Q: I have Release 1A with a Hercules card. When I write a macro
and access a graph via the /GNU command, I cannot return
control to my macro without pressing another key. What is
the problem?
A: When using the Hercules card, it is necessary to press a key
in order to continue execution of a macro. This is not the
case, by the way, with a two-monitor system.
Q: When using the financial functions @PMT, @NPV, @PV and @FV,
are the payments based on beginning or end of period
payments?
A: The functions assume end of period payments.
PrintGraph
Q: After I have printed out my graph, I can't get it back up to
modify it. Why? I saved it?
A: In order to be able to modify a graph, one must use the
/GRAPH NAME CREATE option. This will save the coordinates of
the graph within the worksheet. One can create several
graphs within one worksheet in this way. You must do a /FILE
SAVE in order to save these coordinates. Separate from these
options is /GRAPH SAVE. This will create a picture file of
the graph that is saved independent of the worksheet. This
picture file is the one you print with the Printgraph Disk.
Q: When I use six legends on my graphs, why do they run off the
page?
A: When you have six legends, you can only make very small
legend titles. The solution is to decrease the length of the
legends to a 1 or 2 letter key.
Q: Can I blank out the Y-axis label that says "Thousands,"
"Millions," etc.?
A: No. This scaling is done internally and cannot be overridden
by the user.
Translation
Q: With Release 1A I tried to translate a 1-2-3 file to dBase
II. It seems to translate correctly, but the dBase file is
all garbage. What is wrong?
A: When translating the entire .WKS file, the field headings
must be in Row 1 of the spreadsheet.
Q: What type of files will 1-2-3 accept?
A: 1-2-3 will accept any one of the following data formats: WKS
-- Standard 1-2-3 binary file DIF -- Data Interchange Format
ASCII -- American Standard Interchange Format VC -- Visicalc
file DBF -- dBase II files
Installation
Q: Do I have to put DOS on my disks?
A: It is not necessary to put DOS on your 1-2-3 disks as long as
you aren't using using the FILE MANAGER or DISK MANAGER
programs, both of which use DOS commands. An example is the
DISK MANAGER'S "Prepare" option which uses the DOS FORMAT
command. To use the FILE or DISK MANAGER, DOS must be copied
via the installation procedure.
Q: If I install my 1-2-3 disk for use with a Compaq, does that
mean I cannot use it on the IBM?
A: No. It just means you must reinstall the disks for the IBM
prior to reuse on the IBM. There is no problem with
reinstalling drivers as often as needed.
Hardware
Q: What are the correct HP 7470A pin settings?
A: IBM 1 -- 1 HP 2 -- 3 3 -- 2 7 -- 7 5 -- 6 -- 20 Tie 5, 6
together, connect to 20.
Q: I have just bought Release 1A of 1-2-3. My system has 128K
of RAM. The Tutor Disk is not working properly. Halfway
through I get an "Out of Memory" message. What is wrong?
A: Release 1A of 1-2-3 requires 192K of RAM to operate whereas
Release 1 only required 128K. The higher minimum memory
requirement is a result of additional capability added to
1-2-3 and support of DOS 2.0, an operating system
substantially larger than DOS 1.1.
Worksheet
Q: Whenever I try to use data labels with my pie graph, the
graph will not accept them. What is wrong?
A: Data labels per se are not supported with pie charts. To
achieve the same effect, select /Graph X. Then specify a
range containing the labels you want for your pie slices.
Q: Can I use the same field headings for more than one column when I am
creating a data base?
A: No. 1-2-3 uses field names to identify data in the Data
Query command. It cannot distinguish between duplicate
headings. Field names must be unique.
Q: Can 1-2-3 be displayed in 40 or 132 column modes?
A: No. 1-2-3 runs only in standard 80 column mode.
Q: Where does the "e" come from when doing an @EXP(X)?
A: The letter "e" is a mathematical constant, 2.718, the base of
the natural logarithm. The function @EXP(X) will give the
value of "e" raised to the exponent "X", that is, e x. If you
simply want to raise a number to a given power, simply enter
the number, a caret and then the power. Three raised to the
fourth power is expressed as 3^4.
PrintGraph
Q: Is it possible to print a graph even though I am not able to
view it?
A: Yes, provided you have a graph-supported printer or plotter.
Q: How many graphs can be queued for printing?
A: There is no known absolute limit. Product Support has talked
with individuals who have been able to queue over 25 graphs.
Q: What graphics devices does 1-2-3 support?
A: Here's the list of supported hard copy devices for Release
1A.

Q: I have an Okidata 84 running with Release 1A. The worksheet
prints fine, but I cannot get the graphs to work.
A: You need a STEP 2 PROM upgrade. Okidata 84's manufactured
before February 1983 require the new PROM to function
properly.
Q: My PRINTGRAPH menu tells me I have an FX 80 printer. I have
configured the system for my printer, but it does not retain
the information.
A: FX 80 is the default entry for this item. When you configure
a device for PRINTGRAPH, move the cursor to highlight your
printer choice and hit the [space bar]. Be certain that you
see "#" just to the left of your choice. Then confirm your
choice by hitting [Enter].
If you wish to make this printer/plotter your new default
graphics device, continue by choosing Configure, Save and
Replace.
Q: When I print a graph, my titles get truncated. Is this
normal?
A: Yes. The maximum number of characters that can be used in a
title varies, though you can usually get 36 or 37 depending
on the font and case.
Q: I cannot seem to get my HP7470A Plotter to work with Serial
Port 2. What is my problem?
A: THE HP7470A works only through Serial Port 1 with 1-2-3.
Q: Why is it that the scaling of a graph is different when I
print the graph from when I view the graph?
A: The .PIC file created to print a graph is much more precise
than the graph seen through /GV. This may, at times, result
in a slightly altered scale.
Translation
Q: Where can I get the standards for Data Interchange Format?
A: DIF Clearing House, PO Box 638, Newton, MA 02162. The
approximate charge for technical specs is $6.
Hardware
Q: Does 1-2-3 need a double-sided drive with Release 1A?
A: Yes, this drive capacity is needed for the 1-2-3 System Disk.
Q: What machines will 1-2-3 run on?
A: See 1-2-3 Release News in the World of Lotus
Other
Q: Do we sell parts of the 1-2-3 package separately?
A: As is common in the software industry, we do not offer parts
of the product for sale.
