Global variables and

Hi All Guys,
in my mel script i have a global variable, it is a string array initialize with some values.

this variable is declared and initialized at the beginning pof the script and then it's used by a procedure.

The second time i run the script i get the varning:
"Global variable is already initialized; this occurrence is ignored".

What can i do in order to eliminate this warning?

thank you very much

Hey,

I guess you mainly want to prevent this warning for cleanliness because I don't think it will interrupt the functionality of your script.

I'm not sure what you mean by intialize.. do you mean using the clear command?

Here's a sample of what I would do and it doesn't produce such an error.

global string $test[];
clear $test;
$test=ls;
printls;

proc printls(){
global string $test[];
for($node in $test)
{
print $node;
}
}

Hi Adrian,
well you'r right..it's not an error and my progam still goes on, but i don't want to get such warning...

initialized ... well i have something like this:

global string $text[]={
"Hi, Adrian",
"how, are, you"
};

then

global proc print()
{
global string $text[];
...
}

i've tried adding the clear command but it doesn't work...

bye

I think the problem is that you are declaring and assigning values to the variable at the same time. Declare that variable and then assign a value to it.

global string $text[];
$text=ls -sl;

Instead of:
global string $text[]=ls -sl;
