This article illustrates about label in Microsoft Small Basic programming language.


What Is A Label

A label is a position for the destination from Goto statements.  Classic BASIC language uses a line number instead of a label for Goto.  Following icon represents a label as IntelliSense in Small Basic IDE (editor).

Syntax about Label

To define a label, colon is placed after the label name.

Label:

To refer (jump into) the label, keyword Goto and the label name is needed. Colon is not needed at this time.

Goto Label

 

Label Name

As well as variable name, subroutine name starts with any alphabet or underscore "_" and trails with them or also digits.  Not as syntax but as manner, label name usually starts with upper case character.

Where to Write Labels

You can write label anywhere in your program.  Following list shows the sample to use label.

For i = 1 To n
  If data[i] = target Then
    found = "True"
    Goto Break
  EndIf
EndFor
Break:

But actually if there are lots of labels in a program, that program will become difficult to read.
