CCS C compiler Error !

Hi,

When i run this easy program

#include <16f84.h>

1 main()
2 {
3 int a;
4 int b;
5 a=6;
6 b=6;
7 loop:
8 a=a-1;
9 b=b-1;
10 goto loop;
}

and watch the varible a and b
then run step the program
it gives these reuslts

a=6 b=6
a=0606 b=6
a=0505 b=5
a=0404 b=4
... ....

What is this shit ? Why when i decrement a, value of b changes too in this strange manner !?

Thanks

Compiler error

Read the manual; a=a-1; is suposed to be a=a--1; decrement (--) not (-).

Hi,

I changed the code to

a=a--1;
b=b--1;

But the compiler gives error

You need to go to: **broken link removed**
and do a search for decrement there are examples here. If not ask for help on the forum.

compile error

I tried the code and it compiles;
#include <16f84.h>

main()
{
int a;
int b;
a=6;
b=6;

while (1)

a=a-1;
b=b-1;

}

This also compiles:
#include <16f84.h>

main()
{
int a;
int b;
a=6;
b=6;

while (1)

a=a--;
b=b--;

}

Hi,

Yes, it compiles succeeded.
But the problem is still there.
I use MPASM 6.20.
When he execute b=6
The watch window tells a=0606 b=06

!!!!!

Yes that is true then You must do:

#include <16f84.h>

void main()
{
int a;
int b;
a=6;
b=6;

a=a-1;

while (True)
b=b-1;

}

Hi,

Thanks,
I solved the problem.
The default size in watch window was 16 bit
I changed it to 8 bit
and it worked.
