Put# Statement

将记录写入相对文件，或者将字节序列写入二进制文件。

Use Print# statement to print data to a sequential text file. Use Write# statement to write data to a sequential text file with delimiting characters.

语法:

Put [#]fileNum, [recordNum|filePos], variable

参数:

fileNum: Any integer expression that defines the file that you want to write to.

recordNum, filePos: For relative files (random access files), the number of the record that you want to write.

对于二进制文件 (Binary 访问)，是文件中开始写入字节的位置。

variable: Name of the variable that you want to write to the file.

相关文件的批注: 如果变量的内容与「Open」语句中的「Len」子句里面指定数据的长度不匹配的话，那么介于新写入的数据的末尾和下一条记录之间的空间，将会用你正在写入的文件中的现有数据进行填充。

二进制文件的批注: 将变量内容写入指定的位置，并将文件指针直接插入到最后一个字节后。记录之间不需要留有空间。

示例:


Sub ExampleRandomAccess
    Dim iNumber As Integer
    Dim sText As Variant ' 必须是变量
    Dim aFile As String
    aFile = "c:\data.txt"
    iNumber = Freefile
    Open aFile For Random As #iNumber Len=32
    Seek #iNumber,1 ' 起始位置
    Put #iNumber,, "这是第一行文字" ' 用文字填充行
    Put #iNumber,, "This is the second line of text"
    Put #iNumber,, "This is the third line of text"
    Seek #iNumber,2
    Get #iNumber,,sText
    Print sText
    Close #iNumber
    iNumber = Freefile
    Open aFile For Random As #iNumber Len=32
    Get #iNumber,2,sText
    Put #iNumber,,"This is a new text"
    Get #iNumber,1,sText
    Get #iNumber,2,sText
    Put #iNumber,20,"This is the text in record 20"
    Print Lof(#iNumber)
    Close #iNumber
End Sub
