SELECT / USE

A new Flow Control Statment SELECT / USE / ELSE USE / END SELECT
when one Expression is true and ready with work, then it moves to END SELECT,
no other comparsion will be made.
Look in the generated Pascalsource to see what it does.

SELECT myString   ........... MainValue for Expression can be all what you want ( String,Integer, Byte, Char....)
    USE 'ABC'
  {your Code}
  {your Code}  ............ so many rows if you want
    USE 'XYZ'
  {your Code}
  {your Code}  ............ so many rows if you want
    USE 'Nothing'
  {your Code}
  {your Code}  ............ so many rows if you want
    ELSE USE
  {your Code}
  {your Code}  ............ so many rows if you want
END SELECT

You can but must not use ELSE USE.
