Print | ?

Writes values to the console, then a new line unless it ends with a comma or semicolon.

Syntax

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

Parameters

• expressionlist

Description

Print outputs a list of values to the screen. 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. This has a similar effect to concatenating expressions using + or &.

Print also supports the special expressions, Spc() and Tab(). These can be used to space out expressions, or to align the printing to a specific column.

A new-line character is printed after the values in the expression list unless the expression list is followed by a comma or semicolon. A Print without any expressions or separators following it will just print a new-line.

NOTE: Print resets the Err value after each expression is printed.

NOTE: In graphics mode, Draw String provides a flexible alternative to Print: it prints a string to the screen with pixel positioning, transparent background, and can use a user-supplied font.

Remarks

Dialect Differences

• In the -lang qb dialect, an extra space is printed after any integer number.

Differences from QB

• None, when using QBASIC's variable types in -lang qb, except that no extra space is displayed after any floating-point number. Unsigned numbers are printed without a space before them.
  QB did not support casting for UDTs, so didn't allow them to be Printed.
