Explanation of t #pragma application

[Maverickmax]

Hi

I don't really understand the concept of using #pragma. Can anyone care to explain it to me and maybe few examples?

I want to improve my code by optimising so do you know where can i get example of optimisng my code in Keil Environment?

Re: Pragma

Dear,

The Cx51 compiler offers a number of control directives that you may use to
control compilation. Directives are composed of one or more letters or digits
and, unless otherwise specified, can be specified after the filename on the
command line or within a source file using the #pragma directive. For example:

C51 testfile.c SYMBOLS CODE DEBUG
#pragma SYMBOLS CODE DEBUG

In the above examples, SYMBOLS, CODE, and DEBUG are all control directives.
testfile.c is the source file to be compiled.

For more information take a look @ :
Keil Software — Cx51 Compiler User’s Guide

Chapter 2 : Compiling with the Cx51 Compiler Control Directives section for #pragma
Chapter 6: Advanced Programming Techniques optimizer section for keil optimizer
Appendix C: Writing Optimum Code for hints to writing an optimum code


This PDF File provided with Keil.you can find it @ this place:

<keil installation dir>\C51\HLP\C51.PDF

Good Luck!
