Hi, I am newbie of actionscript. I have a pice of code regarding the map zooming and movement of map by North, west, east… direction.This code is from a CD tutorials. The code is as below:  
[font=Times New Roman][size=3]**on (release, keyPress “\<Left\>”) {**[/size][/font]

[size=3][font=Times New Roman]\*\* if (Number(curxScroll)\<Number(maxXpos)) {\*\*[/font][/size]

[size=3][font=Times New Roman]\*\* setProperty("/map", \_x, Number(getProperty("/map", \_x))+Number(intScroll));\*\*[/font][/size]

[size=3][font=Times New Roman]\*\* if (Number(curZoom) == 0) {\*\*[/font][/size]

[size=3][font=Times New Roman]\*\* curxScroll = Number(curxScroll)+Number(intScroll);\*\*[/font][/size]

[size=3][font=Times New Roman]\*\* } else if (Number(curZoom) == 1) {\*\*[/font][/size]

[size=3][font=Times New Roman]\*\* curxScroll = Number(curxScroll)+Number(intScroll/2);\*\*[/font][/size]

[size=3][font=Times New Roman]\*\* }\*\*[/font][/size]

[size=3][font=Times New Roman]\*\* if (Number(curZoom) == 2) {\*\*[/font][/size]

[size=3][font=Times New Roman]\*\* curxScroll = Number(curxScroll)+Number(intScroll/4);\*\*[/font][/size]

[size=3][font=Times New Roman]\*\* } else if (Number(curZoom) == 3) {\*\*[/font][/size]

[size=3][font=Times New Roman]\*\* curxScroll = Number(curxScroll)+Number(intScroll/8);\*\*[/font][/size]

[size=3][font=Times New Roman]\*\* }\*\*[/font][/size]

[size=3][font=Times New Roman]\*\* }\*\*[/font][/size]

[font=Times New Roman][size=3] **}** [/size][/font]

- This is only part of the code.  
Question here, may I know what is stand for  
**[font=Times New Roman][size=3] 1) setProperty("/map", \_x, Number(getProperty("/map", \_x))+Number(intScroll));?[/size][/font]**  
**[font=Times New Roman][size=3]2)if (Number(curZoom) == 2) [/size][/font]**  
**[font=Times New Roman][size=3]{  
[size=3][font=Times New Roman]** curxScroll = Number(curxScroll)+Number(intScroll/4);\*\*[/font][/size]

[size=3][font=Times New Roman]\*\* } else if (Number(curZoom) == 3) {\*\*[/font][/size]

[size=3][font=Times New Roman]\*\* curxScroll = Number(curxScroll)+Number(intScroll/8);\*\*[/font][/size]

[size=3][font=Times New Roman]\*\* }\*\*[/font][/size]

[/size][/font]\*\*\*\*[font=Times New Roman][size=3]May somebody explain to me the meaning for each function?[/size][/font]\*\*  
**[font=Times New Roman][size=3][/size][/font]**
