Comment (computer Programming) - Examples - in Context - BASIC

BASIC

This BASIC code fragment is a completely functioning program in which the comments describe what the program does for the benefit of novice programmers.

10 REM This BASIC program shows the use of the PRINT AND GOTO statements. 15 REM It fills the SCREEN with the word "WIKIPEDIA" 20 PRINT "WIKIPEDIA" 30 GOTO 20

When run, this program repeatedly prints the word "WIKIPEDIA" (without quotes) in an infinite loop.

In Microsoft BASICs, including QuickBasic, Qbasic, Visual Basic and Visual Basic .NET, any text on a line after an ' (apostrophe) character is placed is marked as a comment. Lines that begin with 'REM' are treated as comments as well, similar to other BASIC dialects. Following is an example in Visual Basic .NET:

Public Class Form1 Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click ' The following code is executed when the user ' clicks the button in the program's window. MessageBox.Show("Hello, World") 'Show a pop-up window with a greeting End Sub End Class

Famous quotes containing the word basic:

    “We can’t nourish our children if we don’t nourish ourselves.... Parents who manage to stay married, sane, and connected to each other share one basic characteristic: The ability to protect even small amounts of time together no matter what else is going on in their lives.”
    —Ron Taffel (20th century)

    “The basic test of freedom is perhaps less in what we are free to do than in what we are free not to do. It is the freedom to refrain, withdraw and abstain which makes a totalitarian regime impossible.”
    —Eric Hoffer (1902–1983)

    “When you realize how hard it is to know the truth about yourself, you understand that even the most exhaustive and well-meaning autobiography, determined to tell the truth, represents, at best, a guess. There have been times in my life when I felt incredibly happy. Life was full. I seemed productive. Then I thought,”Am I really happy or am I merely masking a deep depression with frantic activity?” If I don’t know such basic things about myself, who does?”
    —Phyllis Rose (b. 1942)
