Unions

Hello I am using CCS v4.099 on a PIC18f26k20 processor. I am trying to compile a simple program with a union, and am getting the error message below the union.

Code:

union
{
int8 uByte[2];
int16 uWord;
} CRC16;

CRC16.uWord = 0xFFFF; // Initialise CRC to 0xFFFF

This error is on the assignment of CRC16.uWord.

Quote:

Error 48 "p2.c" Line 61(3,8): Expecting a (
*** Error 48 "p2.c" Line 61(15,20): Expecting a (
*** Error 43 "p2.c" Line 61(17,23): Expecting a declaration
*** Error 43 "p2.c" Line 61(23,24): Expecting a declaration

This example was from a previous posting so I assume it compiled sometime.
Thanks

The line in bold has to be inside main() or some other function.
It can't be sitting out there alone.
