I am new to pearl.

I have sample perl program.

In that perl file variables are declared as below

#-- Program-wise variables -----------------------------------------------------

my ($sDir,$sClear,$sLine,@tHeaders,@tFields,$sFieldName,%hField,@tValues,

$sDir   = $FindBin::RealBin;
$sClear = `clear`;
$|      = 1;

I can see there are 3 different types of variable declared

1. Starts with $ for example $sDir
2. Starts with @ for example @tHeaders
3. Starts with % for example %hField

What are the difference between these 3 variables.

In the below line

$sDir   = $FindBin::RealBin;

Is it refering to the Recyclw bin folder

Thanks in Advance
