Writes a list of values to a file or device

Syntax

` (Print | ?) # filenum, [ expressionlist ] [ , | ; ]

`

Parameters

filenum

The file number of a file or device opened for Output or Append.

expressionlist

List of values to write.

Description

Print # outputs a list of values to a text file or device. Numeric values are converted to their string representation, with left padding for the sign. Objects of user-defined types must overload Operator Cast () As String.

Consecutive values in the expression list are separated either by a comma (,) or semicolon (;). A comma indicates printing should take place at the next 14 column boundary, while a semicolon indicates values are printed with no space between them.

A new-line character is printed after the values in the expression list unless the expression list is followed by a comma or semicolon.

Note that the comma (,) immediately following the file number is still necessary, even the expression list is empty. In this case a new-line is printed, just as with a normal expression list that doesn't have a comma or semicolon at the end.

Note:

• Using Print # is naturally dedicated to Output/Append Access file mode.

• It is also allowed in Binary/Random Access file mode, but this was never well tested and results may vary.

Examples

start GeSHi

Open "bleh.dat"  For Output As #1
   
    Print #1, "abc def"
    Print #1, 1234, 5678.901, "xyz zzz"
   
    Close #1

end GeSHi

Dialect Differences

• In the -lang qb dialect, an extra space is printed after numbers.

Differences from QB

• None, when using QBASIC's variable types in -lang qb.
• Unsigned numbers are printed without a space before them.
• QB did not support casting for UDTs, so didn't allow them to be Printed.
