Undefined identifiers in .ini file

I trying send characters to the UART in simulation in Keil MDK-ARM using .ini file. This code is from uVision Help.

signal
void
serialA_Z (
void
) {
char
ch;
for
(ch = 
'A'
; ch < 
'Z'
; ch++) {
S0IN = ch; 
/* Send character */
twatch (CLOCK / 900);
} 
/* Repeat */
}

But, there is an undefined identifiers error. Where should be defined these identifiers? It is not in the STM lib. or CMSIS files?
