USAGE
   signed int scddbfrsz(
           signed int handle,
           signed int *length,
           signed int command );

PROTOTYPE IN
   sc_base.h

DESCRIPTION
   scddbfrsz either sets (SC_SETSZ) or gets (SC_GETSZ) the I/O
   cache length (in records) based upon the value of command.

   If the cache length is being set, the current cache will be flushed to
   disk before the buffer is reallocated.

   An I/O cache will be used only if the data file was opened with
   SC_BUFFER in the command field.

EXAMPLE
   /* Get Size */
   #include <stdio.h>
   #include <softc.h>
   #include <sc_base.h>

   void main()
   {
     int dbf, length;

     scdinit(20,0);
     if (scddopenx(&dbf,"TOC.DBF",SC_BUFFER) == SC_SUCCESS) {
       scddbfrsz(dbf,&length,SC_GETSZ);
       printf("%d\n",length);
       scddclose(dbf);
     }
     scdterm();
   }

   /* Get Size */
   #include <stdio.h>
   #include <softc.h>
   #include <sc_base.h>

   void main()
   {
     int dbf, length = 100;

     scdinit(20,0);
     if (scddopenx(&dbf, "TOC.DBF", SC_BUFFER) == SC_SUCCESS) {
       scddbfrsz(dbf,&length,SC_SETSZ);
       printf("%d\n",length);
       scddclose(dbf);
     }
     scdterm();
   }
