Installing Graphmatica:
-----------------------
To be able to use the on-line help facility, you should place the six
.HLP files on the same disk and directory as the executable file. Then,
before you run Graphmatica, change the current drive/directory to where
those files are. For example, to install Graphmatica from the disk in
drive A: to some directory C:\GRAPHICS, you would type:
C:\>copy a:graphmat.* c:\graphics
C:\>copy a:grmat?.* c:\graphics
C:\>copy a:*.gr c:\graphics
and to run the program, you would type:
C:\>cd c:\graphics
C:\GRAPHICS>graphmat
Notes:
------
Please do not edit any of the files GRMAT*.HLP. They are formatted
especially for use under the Graphmatica help view function, broken up
into screens of 23 lines. Altering these files may result in abnormal
page breaks and prevent effective use of the online help.
Graphmatica is also available as a Windows program. See GRAPHMAT.DOC
for instructions on obtaining Graphmatica for Windows 1.3.
For a list of what's new in this version, see Appendix B of GRAPHMAT.DOC.
Version 3.30b patches:
======================
1. Bug in "-" associativity fixed. In version 1.30, I attempted to
simplify parsing of minus signs/negative numbers, with the unexpected
result that expressions like 1-x-y were improperly interpreted as
1-(x-y). I have restored the old method which works fine.
2. Better-precision coordinate cursor, point evaluate and range-selection
numerical displays provide 3-significant digit accuracy across the
whole range to make eyeballing points easier.
To register, print out and send in the form found in REGISTER.TXT
(also found at the end of GRAPHMAT.DOC). Or you can register using
CompuServe's Shareware Registration Database ("GO SWREG"). Read
Appendix D in the manual for information about Shareware.
