There's a way to clear all the RAM(non SFRs) at once?

Again, the device is a PIC24FJ1024GB610 and I'm trying to port PIC18F code to PIC24FJ device.

On PIC18F I was using the following code to clear the GPRs (Non SFR RAM)

Code:

void CleanRAM()
{
#asm
movlw 0x0F
movwf FSR0H
movlw 0x3F
movwf FSR0L
NextByte:
clrf POSTDEC0
tstfsz FSR0H
bra NextByte
tstfsz FSR0L
bra NextByte
clrf INDF0
#endasm
}

I was think in to use pointers but CCS will put that pointer in the same memory that I'm trying to erase(set to zero) so this ain't going to end well.

Any suggestion about how to get this goal?
