Once I fixed the Suite8080 assembler to let db accept uppercase symbols, I was ready to work on a similar fix for dw.

But I got dw uppercase support for free as a side effect of canonicalizing symbols to lowercase when adding 16-bit words to the symbol table, as dw already converted symbols to lowercase before checking for inclusion in the table. This unlocked uppercase symbol support, again for free, for most other 8080 instructions that take an address operand such as lhld, shld, lda, sta, jmp, and more.
