Assigning two 16bit unsigned integers problem

[Ömer Faruk]

Hello friends. İ have a problem about assigning 16bit unsigned int to another. When i compile the program i have 2 errors. Please help me.

In each expression, one of the variables doesn't actually exist.
It could be either.

Remember a variable _only_ exists inside the function it is declared 'in',
unless you declare it outside any function, when it becomes 'global'.

So, since 'deger' exists inside the same function a few lines above, it has to
be 'keyit_1', and 'keyit_2', which either have not been declared at all, or
are declared somewhere which is making them not actually exist at this point.

I'm wondering if it's a 'case' problem ?
You've got KAYIT_1 and kayit_1 in your code.
CCS defaults to 'no case', so both names may refer to the same variable.
I KNOW I've been caught by this in the past......

Without seeing the whole program it is difficult to debug

It's ONLY case sensitive IF you add #CASE at the beginning of your code.
The default is NOT case so 'this', 'THIS',' ThIs','tHIs', 'thiS' are all the same and reference one RAM location.

Since you only posted part of your code, I assumed you didn't add #CASE, so the compiler would use noCASE.

Another thing that can cause this issue, is having something else with the
same name. If (for instance), you have a #define that also uses 'kayit_1',
then the declaration won't actually happen. So:
#define kayit_1 something

then

int16 kayit_1;

doesn't result in kayit_1 being declared. Instead 'something' gets declared.

Now depending on what 'something' is, this may not be a possible
declaration, so then things go wrong....

Similarly using the same name in an enum, can also give problems.
