(Print | ?)

Writes values as text to an open file; a trailing comma or semicolon skips the line break.

Syntax

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

Parameters

• filenum
• expressionlist

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.

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.
