NOTE : This isn't the parser used by mSQL.  The mSQL parser and scanner
are all original code.  This is being made available for anyone wanting
to look at an embedded SQL pre-processor for mSQL as this parser
includes ESQL support.

This is an parser for ISO/ANSI SQL written useing LEX, YACC, and C.
It provides syntax check and a frame for building a completed query processor.
See    ANSI X3.135-1986 and ANSI X3.135.1-198x Addendum 1
       ISO 9075-1987(E) Addendum 1

Unlike the previous SQL parser I posted this one can be process with
a normal YACC so everyone should be able to use it.

There are three parts:
       1. Module       -- This process the module specification and
                       produces function calls to which ever language
                       is specificied.
       2. Embedded     -- This process the embedded SQL specification and
                       produces function calls to which ever language
                       is specificied.
       3. Internal     -- This process SQL command passed to the function
                       interface.

Notes:
       In Module and Embedded you add the code to produce the function
       calls.
       Language specificied for use with Module and Embedded C, COBOL,
       FORTRAN, Pascal, PL/1.
       C as a possible langauge for Module and Embedded is not specificied
       in the ANSI specs.  This is the only place I deveated. 

How to use this package
       Running make will produce the executables module, esql, ansi_sql.
