(Print | ?)
Writes text to the screen
(Print | ?) [ expressionlist ] [ , | ; ]
expressionlist
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.

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 &.

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.

Example
'' print "Hello World!", and a new-line
Print "Hello World!"
'' print several strings on one line, then print a new-line
Print "Hello";
Print "World"; "!";
Print
'' column separator
Print "Hello!", "World!"
Print "Hello World!"
'' print several strings on one line, then print a new-line
Print "Hello";
Print "World"; "!";
'' column separator
Print "Hello!", "World!"
'' printing variables/expressions
Dim As Double pi = Atn(1) * 4
Dim As String s = "FreeBASIC"
Print "3 * 4 ="; 3 * 4
Print "Pi is approximately"; pi
Print s; " is great!"
Dim As Double pi = Atn(1) * 4
Dim As String s = "FreeBASIC"
Print "3 * 4 ="; 3 * 4
Print "Pi is approximately"; pi
Print s; " is great!"
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.
