New Features in Ultimate Calculator v1.8 (upgraded from v1.2)
=============================================================
o User functions now accept multiple parameters. For example:
logx(base,number) = ln(number) / ln(base)
o PRINT command sends output to the printer
o LISTF (also F5) command lists all user functions
o Implicit multiplication. The following for instance are equivalent
2pi(3+5)(2-8) x y <==> 2*pi*(3+5)*(2-8)*x*y
o Commands to change or remove the "ucalc> " and "Answer: " prompts
o EXIT command or ^C can be used as a quick exit
o SHELL command shells to DOS
o LOAD command loads a user file
o WRITE command writes the current session to a file
o CLOSE stops writing to the file opened with the WRITE command
Changes
=======
o To make things more clear, the variable which stores the value of the
previous operation is now 'last'. Variable 'x' also does the same
thing (for compatibility with the previous version of Ucalc).
o UCALC.DEF may now cantain any command. The previous version only
allowed user functions & variables.
o FIX & DIG. The FIX command in the previous version was a misnomer.
Now, the DIG command is what controls the *total* number of digits
displayed, and the FIX command controls the number of *decimal*
digits displayed.
o In the previous version variables could have the same name as
unrelated functions. However, due to the implicit multiplication
feature which has been added, it is no longer recommended that any
variable shares the same name as a function.
o I am trying a new registration incentive. All features that are in
the registered version are present in the evaluation version. The
evaluation copy has a reminder screen upon exit, with a delay which
can be cut short by ESC. I'd like to hear your opinion on it.
Bug fixes
=========
o Screen color attributes are no longer changed by F1 or CLS
o UCALC.DEF in a different directory should no longer cause a problem
o Variables with embedded numeral digits no longer confuse the parser
