1:us Design Goals

Within 1> us, there is internal support for time, state and network, which simplifies some aspects of complex C + + programming.

2> is similar to Java and offers the following features and features.

@ There is no pointer.

@ There is an automatic garbage collection.

@ A simple inheritance class relationship.

At compile time, strong type checking is performed.

@ Like the C/c++/java code familiar use way.

3> to improve the simplicity and power of program development, US sacrificed execution speed. 2: string operator

$ two concatenated strings.

For example: Log ("A" $ "B"); Output "AB"

The $= connects two strings and assigns the value to the previous one.

For example: MyString $= "B"; Equivalent to MyString = MyString $ "B"

@ Connect two strings, with a space between them.

For example: Log ("A" @ "B"); Output "A B"

@= is similar to $=, which is equivalent to a space interval in the middle.

For example: MyString @= "B"; Equivalent to MyString = MyString @ "B"

< alphabetical sort returns true if the first letter of the initial string, the ASC code is less than the first letter of the second string. (Note: case sensitivity is differentiated.) Uppercase ASC codes are smaller than all lowercase letters. ）

Example: "Free" < "Knight"//True

> Alphabetical Sort returns True if the first letter of the initial string, the ASC code is greater than the first letter of the second string. (Note: case sensitivity is differentiated.) Uppercase ASC codes are smaller than all lowercase letters. ）

For example: "Free" < "Knight"//False

<= Alphabetical Sort if the first letter of a string, the ASC code is less than the first letter of the second string, or the two strings are identical, both return true. (Note: case sensitivity is differentiated.) Uppercase ASC codes are smaller than all lowercase letters. ）

For example: "Free" <= "Knight"//True

' Free ' <= "free"//True

>= Alphabetical Sort if the first letter of a string, the ASC code is greater than the first letter of the second string, or the two strings are identical, both return true. (Note: case sensitivity is differentiated.) Uppercase ASC codes are smaller than all lowercase letters. ）

For example: "Free" >= "Knight"//True

' Free ' >= "free"//True

= = Returns True if the two strings are identical (note: case sensitive)

For example: "free" = = "free"//False

"Free" = = "free"//True

! = Returns True if two strings are not exactly the same (note: case sensitive)

For example: "free"! = "Free"//False

"Free"! = "Free"//False

~= returns True if two strings are identical (note: case is no longer differentiated)

For example: "Free" ~= "free"//True

' Free ' ~= "free"//True

-= Removes the same part of the preceding string as B. (Note: case sensitive)

For example: MyString = "Free A:freefree";

MyString-= "free";  Log (MyString); Output "A:free"
