Works fine for me:

4 IMPORT: SystemParametersInfo

VARIABLE PV

SPI_GETSCREENSAVETIMEOUT 0 PV 0 SystemParametersInfo
. 1
PV ? 600

SPI_SETSCREENSAVETIMEOUT 60 0 0 SystemParametersInfo
. 1

SPI_GETSCREENSAVETIMEOUT 0 PV 0 SystemParametersInfo
PV ? 60

First call returned timeout of 600. I set it to 60 then read it back and
it's 60. Note non-zero return codes (1) in all cases.
