Hi everyone!!

I'm using Keil to write code in C, but I love ASM. I have a Phillips 87c52 pre-programmed with PAULMON2, so I have lot of usefull code on it, and I load my programs on a ram/flash rom to test it.

I have a file with the start of the subroutines of the 87c52 rom to call from my ASM programs, but, with C, I dont know how to call them.

Is there a way to do something like this?

in a ASM file:
cout EQU 0x0030 ;Send Acc to serial port

in my C file:

void cout(unsigned char value)
{
mov a, value
acall cout
}


thanks!!
