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