i was wondering how basic games handle high scores. i realize that people store the list to the archive after the game closes, i was wondering how you would detect that. here are my thoughts:
3 states of a particular list
1: archive
2: nonexistant
3: not in the archive
deciphering between groups 1 and 3 is easy, unarchive will unarchive if in archive and leave if in ram. Likewise 2 and 3 is easy, if you set dim as 2 then it wont overwirte the data and you can check if the first element is nonzero. The problem occurs when you need to differentiate between archive and non existant. if you give the command to unarchive, then if it doesnt exist you get an error, the only way i can see around this is if there is a way to detect if a list exists whether its in teh archive or not...is this possible, are my thoughts completely off, is there another way to do this? any help would be appreciated

SetUpEditor LHIGH
If number of scores != dim(LHIGH
LHIGH does not exist in the form you want it to
-
Some information on high scores can be found http://tibasicdev.wikidot.com/highscores.
Also, a couple other nice things about the SetUpEditor command is that it will unarchive a list automatically and that it doesn't modify data in the list.

thanks, i didnt know that it did that, that makes things way easier

wow I didnt knew it unarchived them

It will unarchive it if it is archived , it will create it if it doesn't exist, and it will leave it alone if it is unarchived.
