in thread Scope Between global and my

Ok, here is what my code looks like. (Strict hates this) 

 local(
$ItemNumber,
%CFL, @CFD,  #Customer 
%DFL, @DFD,  #Destination
%IFL, @IFD,  #Item
%MFL, @MFD,  #Master
%SFL, @SFD,  #Description
%UFL, @UFD   #User
);

[download]

How do I also declare these variables our ?

Not like this: 

our local(
$ItemNumber,
%CFL, @CFD,  #Customer 
%DFL, @DFD,  #Destination
%IFL, @IFD,  #Item
%MFL, @MFD,  #Master
%SFL, @SFD,  #Description
%UFL, @UFD   #User
);

[download]

that just does not work.

or like this: 

local our (
$ItemNumber,
%CFL, @CFD,  #Customer 
%DFL, @DFD,  #Destination
%IFL, @IFD,  #Item
%MFL, @MFD,  #Master
%SFL, @SFD,  #Description
%UFL, @UFD   #User
);

[download]

that works, but strict still is not happy.

Sorry to be dense.

    You have to declare (using our) before you can localize. Example follows. 

    # in main file

sub main {
 # declare, then localize:
 our (
  $ItemNumber,
  %CFL, @CFD,  #Customer 
  %DFL, @DFD,  #Destination
  %IFL, @IFD,  #Item
  %MFL, @MFD,  #Master
  %SFL, @SFD,  #Description
  %UFL, @UFD   #User
 );

 local (
  $ItemNumber,
  %CFL, @CFD,  #Customer 
  %DFL, @DFD,  #Destination
  %IFL, @IFD,  #Item
  %MFL, @MFD,  #Master
  %SFL, @SFD,  #Description
  %UFL, @UFD   #User
 );

 # set some values:
 $ItemNumber = 6;

 # call other subs.  Can be in other lexical locations, but MUST
 # be in the same namespace for this 'our' to work!
 child_sub1();
}

    [download]
    # in child file 1:

sub child_sub1 {
 # declare ONLY:
 our (
  $ItemNumber,
  %CFL, @CFD,  #Customer 
  %DFL, @DFD,  #Destination
  %IFL, @IFD,  #Item
  %MFL, @MFD,  #Master
  %SFL, @SFD,  #Description
  %UFL, @UFD   #User
 );

 print "Item: $ItemNumber\n";
}

    Since our has lexically-scoped effect, you would put that declaration at the inner-most necessary lexical scope, i.e. inside each of the relevant subs. But only put the local at the point where you want to "protect", i.e. "save", any current values of these variables, i.e. in your "main" sub -- probably just below the our declaration.

      Thanks, that does answer the question. I still think I must be missing something though. But, I have the code working, and I only wince a little when I see that section.

      Again, thank you so much for your help. You and the Monestary are really helping my birth into the world of perl.
