[Basic] - Memory overflow

Treefrog · Post by **Treefrog** » Fri 10 Mar, 2006 2:06 am

Been working on a menu system for the past week or so, and just got a couple versions finally working. When I scan a lot of entries, however, the calc comes up with a memory shortage, even with a couple thousand in ram. I'm only using an if:then statement, and while hearing about problems, have not yet encountered any until now.

Can I get some help or any informative knowledge? Thanks.

ERR:OVERFLOW or ERR:MEMORY?

Memory

Well it has to be what's Ans or that you have too many If statements not closed yet.

Code: Select all

If X=1:Then
something
If A=2:Then
something
If B=3:Then
something
If C=4:Then
...
etc

So it could be a combination of both, since each if statement is about 40 bytes I believe and if your messing with Matrices or Lists that can eat up more memory. And if you don't have much memory to start with then that could add to it.

You can post the code useing this and we can try to help you better.

If you GOTO out of an If block, then it leaves junk on some kind of stack, eventually leading to a memory error. You might be able to use an End after a label to get around it, or just make any IF that uses a goto only a single line long.

I'll post the code when I get back home.

It's in only one IF command, I believe, but does use a lot of list and Ans commands. If I can spot any goto issues, I'll fix that as well.

Yes dwedit is correct, I will take a look at the code when I get a chance.

Sorry, I've been a bit sick this week, so I haven't had time to post. I changed a bit of the If:Then statements, giving a lot less memory errors. I'll code a bit more of the program, and see if I can keep them down.

Thanks for the help!

You've got enough End statements to go with your If:Then/While/Repeat/For/ect. statements? This is often a cause of such errors. Of course, this usually also causes the program to not work properly... However, if you have say a long list of instructions and then a Goto to take it back to the top this can happen right under your nose. Does the program appear to "slow down" before the error?
