 *  $ARGUMENTS$
 *      <xField>    A valid field name
 *

 *
 *      <cDatabase> An valid alias name
 *  $RETURNS$
 *      None
 *  $DESCRIPTION$
 *      This command declares the names of fields <xField> (and <xFieldn> and
 *      following) with an optional alias identifier as <cDatabase> for each.
 *      This command allow  Harbour to resolve any reference to a field
 *      specified in the field listby viewing it as a field when it is not
 *      referenced by an alias.If a field is not listed in this list and it
 *      is not  explicity tagged with an alias indentifier,it may be viewed
 *      as a memory variable,which may cause run-time errors.This command
 *      has no effect on memory variables or on field reference buried within
 *      a macro expression.
 *  $EXAMPLES$
 *      Func main

 *      Initializes a local memory variable or array
 *  $SYNTAX$

 *  $ARGUMENTS$
 *      <xVar>    Name of a memory variable or array.
 *
 *      <xInit>   Value to be assinged to a variable or array
 *  $RETURNS$
 *      None
 *  $DESCRIPTION$
 *      This command created a LOCAL memory variable or array.The name
 *      of either is specified in <xVar>.If more then one variable is being
 *      initialized with the LOCAL command,separate each entry with a comma.
 *      If a variable or an array is to be assingned a start-up value,that
 *      expression may be specified in <xInit> and folling.Is Strong type
 *      compile mode is used, the Compiler will check if the value recived
 *      matchs the type specified in <xType>.
 *
 *      LOCAL varibles are symbols generated at run time and are resolved
 *      at compile time.The visibility and life span of a LOCAL variable or
 *      array is limited to the function or procedure in which it is defined.
 *
 *      No macro expansions are allowed in the LOCAL declaration statement.
 *
 *      No Harbour command other then FUNCTION,PROCEDURE,PUBLIC,PRIVATE,
 *      PARAMETERS,MEMVAR,STATIC and FIELD,may precede the LOCAL command.
 *
 *      LOCAL array reference may not be initialized(i.e.,assigned values)
 *      on the same command line as the LOCAL command statement.This can be
 *      done later in the program.
 *
 *      LOCAL variables and arrays are not affected by the RELEASE command.
 *  $EXAMPLES$
 *      Function Main2()
 *      Local n , lVar
 *
 *      n := IIF( lVar, 'A', 3 )
 *      n := 2

 *  $DESCRIPTION$
 *      This command tells the compiler to resolve any reference to a memory
 *      variable designated within this list s if it possessed an explicit
 *      memory variable alias with either the M-> or MEMVAR-> prefix.Only
 *      those memory variables that do not contain any such explicit are
 *      affected by this command.Those memory variabls within macro
 *      expansions are not affected by this command.
 *
 *      The MEMVAR declaration must apear before any executable commands;it
 *      is similat to the LOCAL,STATIC,FIELD,PARAMETERS,FUNCTION, and
