How to transfer array between procedures?

[goleafsgo]

You could get the array somehow in one proc and then pass it to the other proc so they both work on the same array.

global proc procA()
{
string $sel[] = `ls -sl`;
...
procB($sel);
}

global proc procB(string $arr[])
{
...do something with $arr here...
}

or another way you could do it is something like this:


global proc string[] selectItems()
{
string $sel[] = `ls -sl`;
return $sel;
}

global proc doStuff()
{
string $selection[] = `selectItems`;
for ($obj in $selection)
{
print ("\n"+$obj);
}
}


what is happening is that whenever the procedure selectItems is called, it returns a string array (you could specify any variable type in there). The return command populates that array with the value dictated inside the procedure.

when 'doStuff' is called, it fills the $selection variable with the array returned by selectItems and then you can do stuff to the objects in that array.

Hi,Tim and Norb, Thank you very much !!! I figure it out . Both methods works well, personally I prefer the "return array" one.
Thank you guys ,you really help me out!!:thumbsup:
