porting codes from Microchip C18 compiler to CCS C Compiler

[pdswar]

The following is portion of a code that was written for Microchip C18 compiler while using PIC18C601/801 microcontroller.

..................................................................................

const char ROMpict[3][24][5];

char LineNow = 0; //Line counter for NKKsmartswitch
char Buffer = 0; // buffer for shifting out to NKKsw
char ucByte; // byte counter, 5 bytes per line
int uiCtrR = 0; // count display updates (red LED)
int uiCtrG = 0; // count display updates (grn LED)
int uiCtrP = 0; // count display updates (picture)
char ucPicture=0; // picture 0 will be displayed
char RAMarray[24][5];


void LeftShiftNKKDat(unsigned char byte)
{
DIN=((byte & 0x80)!=0);
SCP = 1;
SCP = 0;
DIN=((byte & 0x40)!=0);
SCP = 1;
SCP = 0;
DIN=((byte & 0x20)!=0);
SCP = 1;
SCP = 0;
DIN=((byte & 0x10)!=0);
SCP = 1;
SCP = 0;
DIN=((byte & 0x08)!=0);
SCP = 1;
SCP = 0;
DIN=((byte & 0x04)!=0);
SCP = 1;
SCP = 0;
DIN=((byte & 0x02)!=0);
SCP = 1;
SCP = 0;
DIN=((byte & 0x01)!=0);
SCP = 1;
SCP = 0;
}

void PlayROMInv(char ucPictNum)
{
for (ucByte=0;ucByte<=4;ucByte++)
{
Buffer=~(ROMpict[ucPictNum][LineNow][ucByte]); //Load Buffer
LeftShiftNKKDat(Buffer);
}
}

void PlayROMNom(char ucPictNum)
{
for (ucByte=0;ucByte<=4;ucByte++)
{
Buffer=ROMpict[ucPictNum][LineNow][ucByte]; //Load Buffer
LeftShiftNKKDat(Buffer);
}
}

void PlayRAMNom(void)
{
for (ucByte=0;ucByte<=4;ucByte++)
{
Buffer=RAMarray[LineNow][ucByte]; //Load Buffer
LeftShiftNKKDat(Buffer);
}
}

---------------------------------------------------------------
When I tried to modify the above codes into following, so that I can use it for PIC 18F6722 with CCS C Compiler, I am recieving 100 Errors which says

-Expecting an identifier

-Expecting a declaration (95% of errors)

----------------------------------------------------------------
#define FLM PIN_F3 //FLM is on PORTF,3 (first line)
#define LP PIN_F2 // LP is on PORTF,2 (line load)
#define SCP PIN_F1 //SCP is on PORTF,1 (clock)
#define DIN PIN_F0 //DIN is on PORTF,0 (data in)
#define BLED PIN_F5 //Blue LED (low is on)
#define DOUT PIN_F4 //DOUT is on PORTF,4 (data in)


void LeftShiftNKKDat(char byte)
{
output_bit(DIN,((byte & 0x80)!=0));
output_high(SCP);
output_low(SCP);
output_bit(DIN,((byte & 0x40)!=0));
output_high(SCP);
output_low(SCP);
output_bit(DIN,((byte & 0x20)!=0));
output_high(SCP);
output_low(SCP);
output_bit(DIN,((byte & 0x10)!=0));
output_high(SCP);
output_low(SCP);
output_bit(DIN,((byte & 0x08)!=0));
output_high(SCP);
output_low(SCP);
output_bit(DIN,((byte & 0x04)!=0));
output_high(SCP);
output_low(SCP);
output_bit(DIN,((byte & 0x02)!=0));
output_high(SCP);
output_low(SCP);
output_bit(DIN,((byte & 0x01)!=0));
output_high(SCP);
output_low(SCP);
}

Should I use bit_test(byte) instead of ((byte & 0xXX)!=0)?

[PCM programmer]

Don't use words like "byte" as a variable name. "Byte" is a data type.
CCS has this statement in all of its include files:

Thank you PCM Programmer

Replaced 'byte' with 'data'.

No ERRORS

Or -

use #case to make the compiler case sensitive, so byte the variable has a different name than BYTE the definition.
