==========================================================================
First, a BIG thank you to all of our registered users for their comments
(and registrations) which have help us to make InstaCalc PC Magazine's
Editor's Choice among low cost spreadsheets (February 16, 1988). We
appreciate your support and confidence in our products.
==========================================================================
If you have questions, you can now ask them via EPLEX on CompuServe. Send
your questions to ID 73250,3163.
The on-disk documentation has been compressed to fit on the disk. To print
out this documentation, use the program named PRINTDOC.COM
InstaCalc V2 uses a different file structure than version 1. Your old
version 1 files must be converted over to the new format using the program
CONVERT.COM.
InstaCalc uses an overlay structure. This means that the InstaCalc program
actually consists of 3 different files; INSTA.COM, INSTA.000, and INSTA.001.
INSTA.COM is the main part of the program. INSTA.000 and INSTA.001 are
overlay files which contain various features and functions of InstaCalc.
When InstaCalc needs to access one of these features or functions, it reads
the code for that feature in from INSTA.000 or INSTA.001. The advantage of
using an overlay structure is that the program uses up less memory, thereby
freeing up more RAM to put your spreadsheets in.
If you place the overlay files (INSTA.000 and INSTA.001) on a hard disk or
in a RAM disk in extended memory, you should not notice any significant
delay when these features are accessed. If the overlay files are on a
floppy disk, you may notice a small delay when accessing these features. If
you have a floppy based system and cannot tolerate the short delays, (or if
you want to free up both disk drives) you may place the overlay files in a
RAM disk.
InstaCalc needs to know where you place the overlay files. By default,
InstaCalc assumes that the overlay files are in the directory where you
start up InstaCalc. If you place the overlay files in a RAM disk or in a
directory other than where you start the program, then you must run the
setup program to create a configuration file which tells InstaCalc where you
put the overlays.
The setup program can also be used to tell InstaCalc where you placed the
help file. It will also let you customize the screen colors which InstaCalc
uses.
RANGE NAMES
You can now give a name to a cell or range of cells. This name can then be
used anywhere that a cell or range reference can be used.
SPREADSHEET LINKING
You can now link multiple spreadsheets together.
LOTUS RELEASE 2 IMPORTING
You can now import both versions of Lotus 1-2-3 files (WKS and WK1).
IMPORTING AND EXPORTING FILES FROM OTHER SOFTWARE PACKAGES
(INCLUDING EXPORTING 1-2-3 FILES)
You can now import from:
- DIF files
- dBase II files
- dBase III files
You can now export to:
- Lotus 1-2-3 files (R1 and R2)
- DIF files
- dBase II files
- dBase III files
TEXT FUNCTIONS
You can now use text strings in formulas (at least the ones that are capable
of providing useful information from text). Several existing @functions now
support text arguments, and several new text functions have been added.
OTHER NEW FUNCTIONS
@ISNUM(x) returns TRUE if x is a number.
@ISTEXT(x) returns TRUE if x is text.
@ERROR returns error as its value.
@INDEX("range name",ColOffset,RowOffset) returns the value of the cell in
"range name" which is RowOffset rows and ColOffset columns from the first
cell in "range name". The top row of the range has a RowOffset of 0 and the
left column of the range has a ColOffset of 0.
TITLE LOCKING
You can lock (hold) title rows and columns on the screen.
NEW CELL FORMATS (AND COMMA OPTION)
There are 2 new ways to display numerical values on the screen:
Hidden and General
NOTE: The General format is now the default format.
The currency, fixed, and percent formats now allow you to specify commas to
be used to make large numbers more readable.
SORTING A RANGE
You can now sort a range of cells by row or column.
GRAPHICS (EXPORTABLE)
InstaCalc now allows you to create simple bar graphs from the data in your
spreadsheet. Once the graph has been drawn on the screen you can press the
[F8]EXPORT key to export the graph to the application program you popped
InstaCalc up from.
ENHANCED DIRECTORY LISTING CAPABILITY
The directory listing command /File Files now asks for a file mask.
The /File Files command now also lists any subdirectories which match the
mask you provide. Directories will be highlighted on the display.
SUPPLYING A FILE NAME ON THE COMMAND LINE
If you want to start up with a particular file, you may now supply the file
name on the command line and that file will be loaded when the program comes
up.
FULL PATH SUPPORT WHEN LOADING/SAVING FILES
You may now Load or Save files from another directory without having to
change directories with the /File Directory command. Simply type in the
full path name when you are asked for a file name.
INSERT/OVERWRITE MODE REMAINS CONSTANT
When you select insert mode, it will now remain in effect until you change
it (it doesn't go back to overwrite mode as soon as you finish editing).
AUTOCALC ITERATION COUNT
You can set a recalculation interation count so that InstaCalc will make
more than one pass through the spreadsheet on each recalculation.
