Please help

I am using CCS version 3.190, PIC16F877
The program does not enter the 'for' loop in the function.
After entering the function, the program counter cursor jumps straight to the row of the loop 'for' and then up to the open bracket of the function with the next step and stuck there.

void DecodeRxPacket(void)
{
BYTE i ;

for (i=1; i<FrameSize; i++)
{

}
}

Where and how is FrameSize declared?

Is FrameSize declared as a byte?

What is the value of FrameSize when you call the function?

[alexz]

BYTE FrameSize ;
FrameSize gets value normaly 7, before calling the function

Can you do a printf before the for loop to look at the value?

Do you have only a single FrameSize variable declared in your application?

[alexz]

yes just a single.
I have also tryed with a constant

Can you post the complete code inside the for-loop? I presume you have something there?

Have you redifined the BYTE type? (Normally it is unsigned, did you define it as signed?)

Is it when you run the debugger you experience this, or does your program "hang" when it is running on the PIC? (And if so, are you sure it is really in the for-loop you have a problem and not somewhere else?)

It is sorted now thank you.
