Local variables

It is best to use one compound variable for all local variables of 
routines declared without the <PROCEDURE keyword instruction. 
The reason: In this case you need only the stem of this compound variable 
as parameter for the keyword instruction <DROP at the end of the routine 
to delete all local variables. Likewise, you can use this one stem to 
initialize your local variables all at once or to assign them all the same 
value at some point in the program. 
And, of course, if you're using unique stems for all procedures, your 
local variables can't interfere with your global variables (or with the 
local variables of other procedures).   

Note:   See Copy the Queue into a compound variable for a working example.
