I was playing around with more stat sprites today, using some sprites from Mario. I ran the program and liked the sprites. I didn't like the side-effect. After some investigating I found that the program lost about 4k of RAM after running. I don't know how it does this, so I was hoping someone could explain. Here's the code:

If it loses around 4k of memory on your calcs, then at least I know it isn't just my calc. Most of the code I have used in many other programs, so I was suprised that this happened.

looks like there are still issues with sourcecoder and ()/{}

other than that, I would have though it to be something like forgetting to delete lists after running or something.

is it every time you run? or just the first?

Well whenever I run the program I am left with 18k of RAM. I only lose the 4k RAM the first time I run the program after a RAM reset. So everytime I reset the RAM, this program sets it back down to 18k.

makes me think you are forgetting to delete a variable somewhere. check all your RAM variables.

Well that's what I thought at first. I've been doing this a few times and every time I check everything is either archived or the variables have been deleted. I just checked it again and got the same result.

after running it hit 0 and then enter about 30 times

This will clear out the Ans variable, which might free up the missing ram

Yes thank you. Adding ClearEntries at the end of the program worked. I guess I missed that since it didn't show up in the memory menu.

although Im not sure if that clears Ans too....

and what is Ans after a RAM clear?

[edit]
that doesn't clear ans, just the entries menu.

a RAM clear sets ans to 0.

Clear Entries does NOT clear Ans, but Ans itself only represents the last variable, so thats not a big deal (unless the last var)

Ans after a ram clear is 0

so


Code:
0
Clear Entries


would clear out Ans and all entries

[EDIT] seems like you figured this out yourself Wink

Ans is 0. I added both ClearEntries and 0 at the end of the program just in case ClearEntries didn't get Ans. It's all good now.

Superb. Sounds like that 4k was going to Ans after all.
