Put# Statement
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 from which 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 Len clause of the Open 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 ' 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 ' 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 Sub ExampleRandomAccess Dim iNumber As Integer Dim sText As Variant ' Must be a variant Dim aFile As String aFile = "~/data.txt" iNumber = Freefile Open aFile For Random As #iNumber Len=32 Seek #iNumber,1 ' 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
