Code:

r8     r9b     r10b   r13b   
r9     r9d     r10d   r13d   
r10    r9l     r10l   r13l   
r11    r9w     r10w   r13w   
r12    rax     r11b   r14b   
r13    rbp     r11d   r14d   
r14    rbx     r11l   r14l   
r15    rcx     r11w   r14w   
r8b    rdi     r12b   r15b   
r8d    rdx     r12d   r15d   
r8l    rip     r12l   r15l   
r8w    rsi     r12w   r15w   
       rsp

I do not know assembler 64 bit (very little).
Of all possible registers in 64 bits, which are those that can be used in "addressing mode".
For example, with 32 bits asm, "al, ah, bl, bh ..." are not allowed ... with 64 bits asm which are allowed ?

thank you.

In fasm's TABLES.INC you can find "address_registers" table. It contains all the register names than can be allowed in addressing.

If you use the TABLES.INC structures for the register and instruction detection then Wink can also work with fasmwarm without modification.

no, i do not use the TABLES.INC structures.
It was just to know all the register names than can be allowed in 64bits addressing.
I don't use anything from fasmw, the Wink_parser is 100% "Wink".
I work only on the lines that "PREPROCE.INC" sends to "proc fasm_syntax.
Wink intercepts the lines at this level!
Having say that, it's more complex that only this sentence ! Smile

(the compiler is also modified to accept multiline comments.)

well, back on topic,
When a jump_opcode is used, then i would like to accept only the words allowed in addressing.
Once a word not allowed in the addressing is used, the highlighting stops.
like this,
