Adding Problem

Hi All,

I have created 2 variables

1. Test varchar(10);

2. File_change(100);

In script I have done like this

$Test = '00000049';

print( $Test );

print values is: 00000049, After I want to add 1 to this value, for that i have created script like below

$File_Change = $Test + 1;

print( $File_Change );

but i am getting print value: 50

even i tried with Concationation(||) operator

$ $File_Change = $Test || '+ ' ||1;

This time I am getting print value 00000049+1

But I want to get "00000050" Can anyone please guide me how to do this.

Thanks
