What are the commands for saving and loading variables? For example: on program start, load varScore. if players score > varScore then save the new highscore in varScore

SAVE "TXT:HISCORE", STR$(HISCORE) LOAD "TXT:HISCORE", 0 OUT _$ HISCORE=VAL(_$)

alternately: HISCORE=VAL(LOAD("TXT:HISCORE",FALSE))

Thanks!
