ByVal or By Ref?

[starlight849]

I have a very simple question. If I am calling a subroutine and passing in StringA by value.. Then I declare a new variable in the subroutine ( we can call it StringB) and want to return StringB back.

How will StringB return? Will it be byval or byref? Does perl have a default way of assigning this?

StrB is not going back unless you assign its value to StrC which would have to be a parameter. If you use strB as a parameter you can not declare it in the sub.

sub(byval strA, strC)
dim strB
strB = strA
strC = strB
end sub
 

To pass the value back, you have to assign it value to the second parameter because its byRef. Nothings going back in strA.
