Write # Statement

Writes data to a sequential file.


Write #filenumber, [ outputlist ]

The Write # statement syntax has these parts:

filenumberRequired. Any valid file number.
outputlistOptional. One or more comma-delimited numeric expressions orstring expressions to write to a file.

Remarks Data written with Write # is usually read from a file with Input #. If you omit outputlist and include a comma after filenumber, a blank line is printed to the file. Multiple expressions can be separated with a space, a semicolon, or a comma. A space has the same effect as a semicolon. When Write # is used to write data to a file, several universal assumptions are followed so the data can always be read and correctly interpreted using Input #, regardless oflocale:

  • Numeric data is always written using the period as the decimal separator.

  • For Boolean data, either #TRUE# or #FALSE# is printed. The True and Falsekeywords are not translated, regardless of locale.

  • Date data is written to the file using theuniversal date format. When either the date or the time component is missing or zero, only the part provided gets written to the file.

  • Nothing is written to the file if outputlist data isEmpty. However, for Null data, #NULL# is written.

  • If outputlist data is Null data, #NULL# is written to the file.

  • For Error data, the output appears as #ERROR errorcode#. The Error keyword is not translated, regardless of locale.

Unlike the Print # statement, the Write # statement inserts commas between items and quotation marks around strings as they are written to the file. You don't have to put explicit delimiters in the list. Write # inserts a newline character, that is, a carriage return-linefeed ( Chr( 13 ) + Chr( 10 ) ), after it has written the final character in outputlist to the file.

Note You should not write strings that contain embedded quotation marks, for example, "1,2""X" for use with the Input # statement: Input # parses this string as two complete and separate strings.


This example uses the Write # statement to write raw data to a sequential file.

Open "TESTFILE" For Output As #1    ' Open file for output. 
Write #1, "Hello World", 234    ' Write comma-delimited data. 
Write #1,    ' Write blank line. 

Dim MyBool, MyDate, MyNull, MyError 
' Assign Boolean, Date, Null, and Error values. 
MyBool = False : MyDate = #February 12, 1969# : MyNull = Null 
MyError = CVErr(32767) 
' Boolean data is written as #TRUE# or #FALSE#. Date literals are  
' written in universal date format, for example, #1994-07-13#  
 'represents July 13, 1994. Null data is written as #NULL#.  
' Error data is written as #ERROR errorcode#. 
Write #1, MyBool ; " is a Boolean value" 
Write #1, MyDate ; " is a date" 
Write #1, MyNull ; " is a null value" 
Write #1, MyError ; " is an error value" 
Close #1    ' Close file.
