This really is an important feature, I had to work around this some time ago and it can get pretty annoying fairly soon.
The minimal syntax typically supported is: label: db 'f','o','o' label: db "mystring",0A,0D,'$' i.e. single quotes for single bytes, and double quotes for multiple bytes. The built-in assembler is not especially good at handling those "pseudo instructions" (i.e. macros etc): http://www.tortall.net/projects/yasm/manual/html/nasm-pseudop.html db 0x55 ; just the byte 0x55 db 0x55,0x56,0x57 ; three bytes in succession db 'a',0x55 ; character constants are OK db 'hello',13,10,'$' ; so are string constants dw 0x1234 ; 0x34 0x12 dw 'a' ; 0x61 0x00 (it's just a number) dw 'ab' ; 0x61 0x62 (character constant) dw 'abc' ; 0x61 0x62 0x63 0x00 (string) dd 0x12345678 ; 0x78 0x56 0x34 0x12 dd 1.234567e20 ; floating-point constant dq 0x123456789abcdef0 ; eight byte constant dq 1.234567e20 ; double-precision float dt 1.234567e20 ; extended-precision float source: http://www.nasm.us/doc/nasmdoc3.html There are suggestions to replace the assembler with a more feature-complete solution: https://bugs.launchpad.net/gnusim8085/+bug/579336 -- Assembler does not support DB 'string' https://bugs.launchpad.net/bugs/579316 You received this bug notification because you are a member of GNUSim8085 developers, which is subscribed to gnusim8085. Status in gnusim8085: Confirmed Bug description: All 8085 assemblers I've seen support the DB 'string' construction but not this one. I've attached a patch to allow string declarations too. There is a known minor bug: consecutive spaces inside strings are compressed to just one space. To correct this I would have to break to much of the existing program structure and I'd rather not. Appart from the above minor bug, strings enclosed in single or double quote are now allowed in DB and commas inside strings are handled correctly. _______________________________________________ Mailing list: https://launchpad.net/~gnusim8085-devel Post to : [email protected] Unsubscribe : https://launchpad.net/~gnusim8085-devel More help : https://help.launchpad.net/ListHelp
