  oracchf : Check cursor cache consistency flag. If set AND oradbgf
            is set, then directs SQLLIB to perform cursor cache
            consistency checks before every cursor operation
            (OPEN, FETCH, SELECT, INSERT, etc.).
  oradbgf : Master DEBUG flag. Used to turn all DEBUG options
            on or off.
  orahchf : Check Heap consistency flag. If set AND oradbgf is set,
            then directs SQLLIB to perform heap consistency checks
            everytime memory is dynamically allocated/free'd via
            sqlalc/sqlfre/sqlrlc. MUST BE SET BEFORE 1ST CONNECT
            and once set cannot be cleared (subsequent requests
            to change it are ignored).
  orastxtf: Save SQL stmt text flag. If set, then directs SQLLIB
            to save the text of the current SQL stmt in orastxt
            (in VARCHAR format).
  orastxt : Saved len and text of current SQL stmt (in VARCHAR
            format).
  orasfnm : Saved len and text of filename containing current SQL
            stmt (in VARCHAR format).
  oraslnr : Saved line nr within orasfnm of current SQL stmt.
 
  Cursor cache statistics. Set after COMMIT or ROLLBACK. Each
  CONNECT'd DATABASE has its own set of statistics.
 
  orahoc  : Highest Max Open OraCursors requested. Highest value
            for MAXOPENCURSORS by any CONNECT to this DATABASE.
  oramoc  : Max Open OraCursors required. Specifies the max nr
            of OraCursors required to run this pgm. Can be higher
            than orahoc if working set (MAXOPENCURSORS) was set
            too low, thus forcing the PCC to expand the cache.
  oracoc  : Current nr of OraCursors used.
  oranor  : Nr of OraCursor cache reassignments. Can show the
            degree of "thrashing" in the cache. Optimally, this
            nr should be kept as low as possible (time vs space
            optimization).
  oranpr  : Nr of SQL stmt "parses".
  oranex  : Nr of SQL stmt "executes". Optimally, the relation-
            ship of oranex to oranpr should be kept as high as
            possible.
 
 
  If the symbol ORACA_NONE is defined, then there will be no ORACA
  *variable*, although there will still be a struct defined.  This
  macro should not normally be defined in application code.

  If the symbol ORACA_INIT is defined, then the ORACA will be
  statically initialized. Although this is not necessary in order
  to use the ORACA, it is a good pgming practice not to have
  unitialized variables. However, some C compilers/OS's don't
  allow automatic variables to be init'd in this manner. Therefore,
  if you are INCLUDE'ing the ORACA in a place where it would be
  an automatic AND your C compiler/OS doesn't allow this style
  of initialization, then ORACA_INIT should be left undefined --
  all others can define ORACA_INIT if they wish.
