Int32 and float problems

[Markus]

Hi,

I am programming an 877 and encountering a few problems with int32 and floats. The program is large (takes up \%55 of PIC ROM and \%80 of PIC RAM) and currently uses long's as its largest variable. I am required to change the long's to int32's but when I do the program functions erratically. Normally the program starts with an intro displayed on an LCD display. When I change to int32 it displays garbage and doesn't perform any of the operations required. I have managed to change one long into an int32 and it worked fine, but any more than one the problems occured. Please help.

Markus

There is not much we can do unless you post some code....
Are you using #seperate? If so maybe you have stack overflow?
How much does the RAM/ROM grow when you switch to INT32. How are floats involved?

Thanks to both of you for replying so quick, I also apologise for the numerous posting of the same question, I was getting an error when I tried to post the question, so I assumed they weren't working, I was wrong. I tried to delete the excess but I just got more error's.

I will try to get some of the code to you next week, but to answer your other questions, I'm not using #seperate; when I use one INT32 I get a 5\% increase in RAM and a minimal change in ROM; I'm not using any floats at the moment, I just tried them when the problem occurred with INT32 and found the same problem occurring.
