Writes a record to a relative file or a sequence of bytes to a binary file.
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.
Syntax:
Put [#]fileNum, [recordNum|filePos], variable
Parameters:
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.
For binary files (binary access), the position of the byte in the file where you want to start writing.
variable: Name of the variable that you want to write to the file.
Note for relative files: If the contents of this variable does not match the length of the record that is specified in the \<emph\>Len\</emph\> clause of the \<emph\>Open\</emph\> statement, the space between the end of the newly written record and the next record is padded with existing data from the file that you are writing to.
Note for binary files: The contents of the variables are written to the specified position, and the file pointer is inserted directly after the last byte. No space is left between the records.
Example:
Sub ExampleRandomAccess
Dim iNumber As Integer
Dim sText As Variant REM Must be a variant
Dim aFile As String
aFile = "C:\Users\ThisUser\data.txt"
iNumber = Freefile
Open aFile For Random As #iNumber Len=32
Seek #iNumber,1 REM Position at beginning
Put #iNumber, , "This is the first line of text" ' Fill line with text
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
