Best,

I thought it was buried. In a.l.a, I usually see responses to my
questions before I post them. :) That's a compliment!

Young people??? Frank, I'll be 65 years old (in 25 years).

I'm going to have to print your answer and pour a cup of coffee. Thanks
for elaborating. At first reading, I'm still not sure why one label
declared in masm's uninitialized data gets translated by the assembler as
an offset from @data, while another declared label in the same BSS
section gets translated as an offset from _bss. Shouldn't they both be
translated as offsets from _bss? (or assembled to processor opcode
instructions and data, or "pcode" like you old-timers call it??).

It's very confusing to me when I put some labels in the bss section and
see that the disassembly of the code references to those labels (when
debugging) shows an offset from @data for one label, and an offset from
_bss for another.
