   recordType =  recNormal/recVariable/recTable(1,2,3)
   During parsing, it is always kept -1 ,1 or 0.

   This is used during tree generation...
   During parsing, recordType is always kept 0 for simplification reason
   recordType = 1  =>  it is ITSELF a table (i.e. its syntax is a Sequence)
        = 2  =>  it is a entry (elements under "Entry" are actual elements
        = 3  =>  it is an element. Index values are appended to it
        instead of .0
        = 0  =>  The entry is not in any table,i.e. it is a normal record :)

   Variable tableEntry is used to store the no. of entries the
   table contains,i.e. number of values  for each element of table.
   -1 means it has not been initialized yet.
