  A compound statement is a tool for

  structured programming.  It helps eliminate

  unconditional jumps such as GOTO's.

  A compound statement can be compared to the

  circuit integration technology, such as

  going from the Medium Scale Integration (MSI)

  to the Large Scale Integration (LSI) to the

  Very Large Scale Integration (VLSI), etc.

  For example, originally several electronic chips

  were required to build a small system.

  Some time later these and other chips were integrated into a

  single chip, and similarly other chips were integrated into

  other circuits to make up an even more complicated system.

                 ---->    ----  ---->  \--\ 

                   |--> / ----   /-->  -^--^

                   |  /        ----      ^

            -------  |         ----      |

                     |         ----      |

                     |    ----           |

                 ----     ---- -----------

                          ---- 

 Similarly, one might think about the compound statement as one that

 integrates several other smaller, simple and/or compound statements.
