Well, Ok, but, when I want to see anything about the disks, I've got a symbol 
"SYD" that is "SHOW DEVICE D", and I'm guessing that invokes a non-DCL program, 
which could support larger than 32-bit integers.

I guess it is because I see "DCL" as "Digital COMMAND Language", not "Digital 
PROGRAMMING Language".
