Types :

Functions, Variables and Sub Programs

· Constants : PI = 3.1415926536 … , Infinity, epsilon

· Constants Characters : Alpha,alpha, Beta, beta , …. (Greek alphabets) : Allows to use Greek Alphabets

· Variables: defined by users

· Functions: Currently comes bundled with KDL (and for now, can’t be changed): They return a result

· Subprograms: Currently comes bundled with KDL: they don’t return any result

Variables Types:

Keyword (KDL)	Keyword (Algo)	Input	Goal
Bool	Boolean	True False	Get a Boolean (true or false)
Int	Integer	1, 2, …, 1000,…, 32767 -1,-2,…,-1000,…, -32768	Integer
Doubleint	Long	1,2,…, 2147483647 -1,-2,…, - 2147483648	Integer (but goes more than 32768)
Float	Float	1.2, 1.3, … 16.8 …	Real numbers
Doublefloat	real	16.8 …	Real numbers with more precision
Char	Char	a,b,c,d,…,z	Contains characters
String	String	“KDL”	Contains string of characters
Byte	Byte	1,2,…,255	Integer from 1 to 255
Obj Expr	Object Expression	All of above	Contains anything and everything including expression/1-line function

Assign, 1-line Functions and Processing
Return simple results

Instruction	Usage	Example	Goal
<-	Var <- contain	t<- sin(y) y<-pi	Assign
->	Contain->var	Pi->y sin(t)->z	Assign
?	Var? expr?	Sin(pi)? y?	Return an immediate result after processing variables and constants
??	var??	y??	Return variable type
!?	var!?	t!?	Return variable expression without processing results or constants

Declare variables
There are two ways to define a variable ; I use KDL’s

Instruction	Usage	Example	Goal
Define	Define <var> as <type>	Define x as real	KDL way to define a variable
Var	Var <var>:<type>	Var x:real variable y:float	Algorithm way to define a variable

Sub Programs/procedures (GENERAL)
will not output anything, just do what they were supposed to do
procedures syntax: PROCEDURE VARIABLE

Instruction	Usage	Example	Goal

Write dowrite	Write <message> dowrite <message>	Write Message Dowrite KDL message	Write into screen
Speak	Speak <message>	Speak Hello	Make computer speak message (vocally)
Read	read(var)	Read(x)	Input a variable
Wait	Wait <time>	Wait 2	Wait before going to next command (in seconds) Note: It can be float or integer
Beep	Beep	Beep	Beep from computer (or Speakers for Windows 7)
Script	Script <scriptfile>	Script myscript.txt	Load a script file (or KDL batch file)
About	About	About	About
Exit	Exit	Exit	Exit

Sub Programs/procedures (Directory and files)
Modify files and directory

Cd Dir:change	Cd (path)	Cd C:\users\name\	Change directory
Rd	Rd (path)	Rd c:\users\name\temp rd temp	Remove directory’s files then directory itself
Rdall	Rdall (path)	Rdall temp	Remove All of directories and subdiretories
Rm	Rm (path1)=> (path2)	Rm temp=>temp2	Rename directory
Copy	Copy (file1)=>(file2)	Copy file.mp3=>file2.mp3	Copy file
move	move (file1)=>(file2)	move file.mp3=>file2.mp3	Move/rename a file
Kill	Kill (file)	Kill file.txt	Delete (permantely) a file
Delete	Delete (file)	Delete file.txt	Send file to recycle bin
