I have tried to use IF, ENDIF statement for 8051 in Keil, but got error.

is it possible to use IF, ENDIF statements in 8051 ?

something like this :

CODE:

IF (A>31)

   setb P1.1

ELSE

   clr P1.1

ENDIF

Build target 'Target 1''
linking...
Program Size: data=8.0 xdata=0 code=709
creating hex file from "Final Year Project"...
"Final Year Project" - 0 Error(s), 0 Warning(s).

you can use IF in assembly, rather IF can be used as preprocessor programming part.
which does not come in picture during execution but plays its role when linking the program.

Freddy, it seems to me you are a beginner with 8051. I would suggest to try first Pascal language, get some experience and then, if needed, switch to C, assembler or whatever.

Try Turbo51, it's free!

well there is no limit, but its better to stick to single thread till your problem is different. Like now you have posted in a new thread whereas it could be done in the previous thread only.
