It occurred to me that 'anonymous' labels might be a good
addition to DASM. These
are sometimes called MASM-style local labels, but they are
not just local, they are
totally nameless. The syntax used is:
@@ JMP NXT
SCAN LDA NUM ; ordinary label
CMP #3
BCS @B ; branch to previous anonymous label
JMP ONE
CMP #2
BNE @F ; branch to next anonymous label
JMP TWO
@@ CMP #3
These labels simply identify a line as a target of a branch
instruction. The symbol @F refers to the next line labelled
with @@ and the symbol @B refers to the most recent line
labelled with @@.
The intent is to avoid having to construct artificial or
enumerated names for labels just to satisfy
the requirements of unique labels for the assembler. Long
case-type statements and if-type constructs are easily coded
with this strategy.
(Please, no attacks! This is just a suggestion which other
coders may regard as without merit or borderline dangerous,
but which has been found useful in some commercial
assemblers.)
