sdcc - 在 ASM 中为 SDCC/LCC 编译字符串文字

Question

我正在尝试在 ASM 中为 GBDK 的 LCC 编写字符串文字。我可以编写每个单独的字符并且编译器工作正常。

.D_LINE = 0x0A
;; Works
.db "G", "I", "A", "N", "L", "U", "C", "A", #.D_LINE

但是，当我尝试将字符组合成一个字符串以使其更具可读性时：

.D_LINE = 0x0A
;; Doesn't work
.db "GIANLUCA", #.D_LINE

我得到一个编译错误：

text.s:12: Error: <o> .org in REL area or directive / mnemonic error

有没有办法解决这个问题？
