**
** Modification History:
**
** 1994.12.02 KRT Created function
** 1994.12.05 KRT Made it a function and cleaned it up
** 1994.12.08 KRT Assume Database is open to speed up operation
** 1995.09.15 KRT Use DBF() to find the real table name
** 1995.09.15 KRT Take into account CR+LF in comment fields
** 1996.04.12 KRT Added new properties for Visual FoxPro 5.0
** InputMask / Format / DisplayClass
** DisplayClassLibrary
** 1996.06.01 KRT Added support for Collate sequence on index
** 2002.06.28 DH Added support for auto-incrementing fields
** and filtered primary keys, and changed to use
** INDEX ON ... COLLATE and ALTER TABLE ... COLLATE
** rather than SET COLLATE TO
** 2004.03.19 DH Added support for Blob, VarChar, and
** VarBinary fields
** 2004.05.05 DH Added support for binary indexes

**
** Function Name: GETVIEW(<ExpC>, <ExpC>)
** Creation Date: 1994.12.01
** Purpose :
**
** To take an existing FoxPro 3.0/5.0 View, and generate an output
** program that can be used to "re-create" that view.
**
** Parameters:
**
** cViewName - A character string representing the name of the
** existing view
** cOutFileName - A character string containing the name of the
** output file
**
** Modification History:
**
** 1994.12.01 JHL Created Program, runs on Build 329 of FoxPro 3.0
** 1994.12.02 KRT Added to GenDBC, removed third parameter, cleaned up
** 1994.12.08 KRT Assume Database is open to speed up operation
** 1996.04.12 KRT Added new properties for Visual FoxPro 5.0
** Prepared / CompareMemo / FetchAsNeeded
** 1996.05.14 KRT Added more properties for views
** 1996.05.16 KRT Adjusted for return a blank string instead of a logical
** value on Prepared, etc.. if the field does not exist
** in the database (Version 3.0 database converted to 5.0)
** 1996.05.16 KRT Added the DataType property
** 1996.06.26 KRT Added support for ParameterList
** 1996.07.19 KRT Added support for Offline Views
** 1996.08.07 KRT Added support for BatchUpdateCount, Comment
** 2002.06.28 DH Removed duplicate output of FetchSize property
** 2004.04.14 DH Added support for AllowSimultaneousFetch,
** RuleExpression, and RuleText properties
** 2004.09.22 DH Handled case where UpdateName has quotes (e.g. with
* calculated fields like "Test" AS SOMEFIELD)
