is it a correct program? and what is utils.h?
If it's a correct Keil program?
We can't even read it since you didn't add the proper formatting.
What <lcd.h> and <utils.h> means? That depends entirely on what files you happen to have with these file names, and available in the configured "system" include directories.
Why are you asking? Do you get compilation errors?
yes i do get compilation errors

case 0x01:
if(OUT1==1)
OUT1 = 0;
else
OUT1 = 1;
lcdPrint(M1);
case 0x02:
if(OUT2==1)
OUT2 = 0;
OUT2 = 1;
lcdPrint(M2);
case 0x03:
if(OUT3==1)
OUT3 = 0;
OUT3 = 1;
lcdPrint(M3);
case 0x04:
if(OUT4==1)

OUT4 = 1;
lcdPrint(M4);
}
} } }
So fix them, then!
Is it really that hard to spot & follow the posting instructions: www.danlhenry.com/.../keil_code.png
You get compilation errors. But for some magic reason you don't think it would be to your advantage to post these error messages?
One of the main goals with compilation error messages is to inform the developer of what is wrong. It is then up to the developer to decide how best to rectify this before trying again.

and I am getting following errors:- voice.c(5): warning C318: can't open file 'lcd.h' voice.c(6): warning C318: can't open file 'utils.h' VOICE.C(12): error C141: syntax error near 'P0', expected 'const' voice.c - 1 Error(s), 2 Warning(s).
can't open file 'lcd.h'
I think you should know what it means, as it writes. The compiler cannot find/open the header file 'lcd.h'. You should tell the compiler where it is. Normally you should tell the compiler proper include paths in Options for Target >> C/C++ >> Include Paths
thank you. what about this error VOICE.C(12): error C141: syntax error near 'P0', expected 'const'
Learn your Cx51 User's Guide for proper syntax of 'sfr'.
now these errors are coming into picture compiling voice.c... voice.c(6): warning C318: can't open file 'utils.h' VOICE.C(38): warning C206: 'lcdInit': missing function-prototype VOICE.C(40): warning C206: 'lcdClear': missing function-prototype VOICE.C(41): warning C206: 'lcdGotoXY': missing function-prototype VOICE.C(41): error C267: 'lcdGotoXY': requires ANSI-style prototype voice.c - 1 Error(s), 4 Warning(s).
So - you have picked up some random source code somewhere.
Most probably you have a school project and figured that the code you found seems to be close enough to your task so you want to hand it in and save lots of time.
But one thing with code you have found - you need to understand it. Another thing - you need to make sure you get the complete code. the lcd.h and utils.h files aren't part of the C language but are most probably either extensions supplied by a tool vendor or a library vendor or are written by the same person who wrote the main source file.
Before you have these lcd.h and utils.h files in your configured include path, "your" code will not compile.
So provide a suitable function prototype, then!
You do know what a function prototype is - don't you...?
The prototype (in the style defined by the ANSI standard) is not optional - it is required
You do not need to learn the Cx51 User's Guide in the sense of memorising it by heart; it is a reference document - so you should refer to it when required.
But you do need to spend time gaining familiarity with it - so that you can find your way around easily.
You also need a good understanding of the 'C' Programming language.
One interesting thing with this incomplete program.
Not only are the two header files needed.
But one step later, the linker will also need access to the object code for the actual implementation of whatever functions that the lcd and utils header files happens to mention.
