Description:

A flow control statement that branches unconditionally to a specified line.

Syntax:

The following shows the format of the Unconditional Branch syntax.

Visual Basic & BASIC	C	Java
Goto <line>	Goto <line>;	The Java syntax does not support the Unconditional Branch

The following table lists the elements of the Unconditional Branch syntax.

Element Description

Basic & C Java

<line> Used to specify the target line label that will be branched to.

Operation:

Basic & C Syntax:
When an Unconditional Branch is encountered during the program's execution, the program flow will branch to the target line label specified by the <line> element. The only stipulation on the Unconditional Branch is that the target line label be within the same Function or Procedure that the Unconditional Branch is in.

Java Syntax:
Java only allows structured flow-control statements to be used and therefore does not support the Unconditional Branch.

Remarks:

The Unconditional Branch allow programs to be written in unstructured ways. This can create code that is hard to debug. It is recommended that other flow-control statements be used instead.
As a point of order, the entire ooPIC compiler program does not contain one single Unconditional Branch.

Example:

In the following example, an Unconditional Branch is shown that causes the program flow to branch to the line labeled "LLL" where the statements in <statement2> are executed.. As a result, the statements in <statements1> are never executed.

Visual Basic & BASIC	C	Java
Goto LLL <statements1> LLL: <statements2>	Goto LLL; <statements1> LLL: <statements2>	Not possible.
