PRINT

Writes text to the screen

Syntax:Print [ expressionlist ] [ , | ; ]
Parameters:

expressionlist

list of items to print

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.

For more control over character style and text position in graphics modes, consider using Draw String.

Examples:

'' 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!"

'' 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!"

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.
