| Int declaration inside function? Possible ? |
 Posted: Tue Jan 19, 2010 5:02 pm |

I need to make Int variable inside function:
Like this :
| Code: |
void SOMETHING(void){
int z=3;
....
}
|
However if I try to do that I'm getting an error " Expression must evaluate to a constant".
If I make Int outside of function I can access it from the function.
But to make the code nice-looking I want to make no global variables. |

| One more thing : Is there a short simple method to split Int16 into two Int8 ? |

Post a test program that shows the problem. For example, the test
program shown below compiles with no errors with vs. 4.104.
| Code: |
#include <16F877.H>
#fuses XT, NOWDT, BROWNOUT, PUT, NOLVP
#use delay(clock=4000000)
#use rs232(baud=9600, xmit=PIN_C6, rcv=PIN_C7, ERRORS)
void SOMETHING(void)
{
int z=3;
}
//======================================
void main()
{
while(1);
} |

The manual has a summary page of all CCS functions. It's on page 151
in the Acrobat Reader.

It lists functions by type of use.
If you look at the list of functions in this section, you will quickly find
what you want. (For future reference).

To answer your question, look at the make8() function in the manual. |
