Can we use Global variables and structures declarations in Paged RAM?
If yes, how can we use it? (Whether with #pragma derivative)

In linker file it is stated as
/* paged RAM:                       0x1000 TO   0x1FFF; addressed through RPAGE */
      RAM_F8        = READ_WRITE  0xF81000 TO 0xF81FFF;
      RAM_F9        = READ_WRITE  0xF91000 TO 0xF91FFF;
      RAM_FA        = READ_WRITE  0xFA1000 TO 0xFA1FFF;
      RAM_FB        = READ_WRITE  0xFB1000 TO 0xFB1FFF;
      RAM_FC        = READ_WRITE  0xFC1000 TO 0xFC1FFF;
      RAM_FD        = READ_WRITE  0xFD1000 TO 0xFD1FFF;

MYDATA INTO RAM_FD;  //this is our modification

in variable.c file we are specifying Data seg as
#pragma DATA_SEG MYDATA

Is this the right syntax and method or should we use something else?
