Hi, i'm using Keil C51 c compiler and i need to insert some time critical routines coded in assembly into my c program.
I use the pragmas
#pragma asm

#pragma endasm

I try to compile the thing but i get an "error C272: 'asm/endasm' requires src-control to be active"
So i go into the options and under "compiler control string" i add the "SRC" command. The command appears then listed under "compiler control string".
I start again the compiler and i get a new error:
compiling prova.c...
linking...

Why doesn't it work?
Can you help me?

Thanks.
