need help with tasm code

[jack]

I am studying some code written in Borlands tasm, here's a small snippet.

Code Select Expand


join_: @cld ; Auto-increment index reg.s
@LDS  rsi, [srcBCD] ; Load
@LES  rdi, [dstBCD] ;   pointers
        mov   rbx, [BCDsz]      ; Get byte size of BCD
dec   rbx ; Handy constant

my questions are
1. why @cld, @lds and @les instead of just plain cld, lds and les
2. what about the registers, rsi, rdi, rbx, are they esi, edi, ebx?
thanks in advance.

I didn't know there was a 64 bit version of TASM available. Are you sure its TASM code and not something else ?

no this very old code, btw after scouring through the doc files found out that "@" is used to call a macro, (I think), please disregard this post. :red
<edit> sorry for a stupid post, my appologies, after reading the include files i found out that @cld and the rest are macros, and the registers are equates
so it could be compiled as 16 or 32 bit, that is "rbx" is either bx or ebx"

More like 64b.
