UniPlot.Call	ret = UniPlot.Call(ssFuncName, arg1, ...)
UniPlot.Call2	The UniPlot.Call2 method can be used to invoke a UniPlot function from a different process (ActiveX-Controllern).
UniPlot.Caption	UniPlot.Caption = ssTitle
UniPlot.Height	This property sets the UniPlot window height in pixel.
UniPlot.Left	This property sets the UniPlot window left position in pixel.
UniPlot.Top	This property sets the UniPlot window top position in pixel.
UniPlot.Visible	This property can be used to hide or display the UniPlot window.
UniPlot.Width	This property sets the UniPlot window width in pixel.
UniScript.Call	The UniScript.Call method can be used to invoke a UniScript function from another program (ActiveX-Controllern).
UniScript.Call2	ret = UniScript.Call2(ssFuncName, arg1, ...)
UniScript.Load	Loads a UniScript file.
VariantConvert	Is replaced by vcast.
VariantGetType	Is replaced by vtype.

	Symbol table
LibMain	A UniScript library (.ICL) can have one function with the name LibMain. This function will be called directly after loading the library.
RegisterFunction	RegisterFunction registers a function from a dynamic link library (DLL) to the UniScript symbol table. After a function is registered, the function can be called directly by UniScript.
alias	alias gives a meaningful name to a constant in the program.
clear	clear removes a variable or a function from memory.
eval	eval evaluates the string given as UniScript code.
eval_file	eval_file loads a file with UniScript program code.
evalp	evalp evaluates UniScript program code.
evalp_file	evalp_file loads a file with UniScript program code.
get_prototype	get_prototype returns the prototype string of a UniScript function.
load	load reads files with UniScript commands and functions. Commands are executed and functions are compiled.
loadiclib	loadiclib loads a UniScript library which contains UniScript functions in binary form.
loadlib	Loads a UniScript-DLL (Dynamik Link Library) into memory.
saveiclib	saveiclib saves all loaded UniScript functions in an UniScript Library file.
source	source returns the file name in which the function is located.
stack	stack returns the current function name as well as the function name of the calling functions.
symbols	symbols returns the names and the sizes of variables and functions.
what	what displays the names of the loaded UniScript functions in the command window.
who	who displays the names of the global variables in the command window.
whos	whos displays information about global variables.The variable name is displayed in the first column. The second column contains the variable type (real, complex, string). The third and forth columns display the number of the variable’s rows and columns. The fifth column contains the variable size in bytes.

	Misc
GetWindowsVersion	GetWindowsVersion returns information about the windows version.
IpwInfo	IpwInfo returns the number of streams and the total size of all streams of an ipw file.
IsWin64	IsWin64 checks, if a 64-Bit Windows version is installed.
ShellExecute	ShellExecute opens a file with a program which is registerd for the file type.
exptok	exptok splits a simple arithmetic expression into tokens.
getargs	getargs returns a vector of the arguments passed to UniScript. This function is especily useful for UniScript us.exe.
system	system creates a new process.
us_lock	us_lock locks the Windows message loop while an UniScript function is executed.

	call
config	config sets and retrieves the UniScript configuration.
diary	diary opens and closes a file in which all input and output of the command window will be written.
error	error prints an error message into the command window and terminates the execution of the running program.
format	format sets the output format for the print command.
nargsin	nargsin returns the number of arguments a function was called with.
nargsout	nargsout returns the number of return values a function was called with.
system	system creates a new process.
version	version returns the version string or version number of UniPlot.
find	The find function finds the indices of all matrix elements which do not equal 0.
findfirst	findfirst finds the index of the first element that is not 0.
all	all checks if all elements of a vector or matrix are other than zero (0).
any	any checks if any elements of a vector or matrix are zero.

	Debugging
DebugBreak	DebugBreak sets a break point. The program will stop exection at the function call. interrupted
get_prototype	get_prototype returns the prototype string of a UniScript function.
print	The print command prints the data into the command window
profiler_start	profiler_start starts the profiler. The profiler can be used for analyzing the run-time behavior and performance of programs.
profiler_stop	profiler_stop stops the profiler that has been started with the profiler_start function. The profiler can be used for analyzing the run-time behavior and performance of programs.
source	source returns the file name in which the function is located.
stack	stack returns the current function name as well as the function name of the calling functions.

	Logging
log_add_logger	log_add_logger adds a logger to the list of loggers.
