Remembering and playing back bgm

Hello, I am trying to write a scene in the script section.
I want it to remember the bgm, play a new one, then after a bit I need it to resume the old music after stopping the new music.

ret=Kernel.Audio_bgm_get_position
neither dpes
Audio_bgm_get_position
or any of the other ones found in the Audio script.
And in the SpriteWindow script there isn't a pb script for remembering the bgm as far as I can see.
doesn't work.
I've already used
pbBGMFade(1.0)
pbBGMPlay()

$game_system.bgm_pause
$game_system.bgm_memorize

then afterwards

$game_system.bgm_restore
