Scope scope scope

Ok, so I'm being a complete newbie and getting stuck with scope. How should I be doing this?

PHP Code:


		
			
$fileLoc = "C:/output.txt";

global $file=`fopen $fileLoc "r"`;



global int $readcount = 0;

global string $curval = "";

global int $curframe = 0;



global matrix $frame[18][38];



main();



global proc main(){



    $curval = `fgetword $file`;

    $readcount++;



    while ( size( $curval ) > 0 ) {



        if($readcount == 686){

            $readcount = 1

            drawmatrix();

        }



        if($readcount == 1){

            $curframe = $readcount;

            print ( $curval + "\n" );

        }else{

            addmatrix();

        }



        $curval = `fgetword $file`;

        $readcount++;

    }



    fclose $file;

}



global proc addmatrix(){



    int $count = $readcount - 1;

    

    int $y = 0;

    

    while($count > 38){

        $count -= 38;

        $y++;

    }    

    

    int $x = $count;



    $frame[$y][$x-1] = $curval;



}

I get loads of errors about things not being defined so I'm certain it's a scope issue.

Aha, gotta declare the vars again in each proc.

How do I globally define the $file, since I don't know datatype?

All fixed. To anyone who stumbles across this with the same problems:

1) global variables need to be defined in the procedure as well as outside the proc.

2) file id's can be defined globally by doing:

PHP Code:


		
			
global int $file;

$file = `fopen $fileLoc "r"`;

They can also be defined in one line.

PHP Code:


		
			
global int $file = `fopen $fileLoc "r"`;
