'1.Eval的用法
Dim intA,intB
intA = 10
intB = 20

Wscript.echo (intA = intB)
Wscript.echo Eval( intA = intB )
'2.数学函数
'绝对值
Wscript.echo Abs( -120 )
'Cos,Sin,Tan,
'求随机数
For i = 0 to 10
    Wscript.echo Rnd
Next
'求整数
sgnPI = 3.1415
Wscript.echo CInt( sgnPI )
Wscript.echo Fix( sgnPI )

'求平方根
Wscript.echo Sqr( 16 )

'3.字符串操作函数
'去除空格函数
Dim strLine
strLine = " Spacebar string "
'去除左右空格
Wscript.echo Trim( strLine )
'去除左空格
Wscript.echo LTrim( strLine )
'去除右空格
Wscript.echo RTrim( strLine )

strLine = "ABCDEFGHIJKLMNOPQRSTUVWXYZ"
'去左边的5个字符
Wscript.echo Left( strLine, 5 )
'取右边的5个字符
Wscript.echo Right( strLine,5 )
'从制定的位置去制定长度的字符

'计算字符串的长度
Wscript.echo Len( strLine )
'字符串替换
Wscript.echo Replace( strLine, "AB","BA" )
'比较两个字符创
Wscript.echo StrComp("abc","ABC")
Wscript.echo StrComp("abc","abc")


'对字符串进行分割
strLine = "Hello VBScript,I Love it"
strArray = Split( strLine )
For i = 0 to UBound( strArray )
    Wscript.echo strArray( i )
Next
