Works for me. But your example is broken.

Code:

flat assembler  version 1.73.31  (16384 kilobytes memory)

test.asm [6]:
xOp h*j ;display h
test.asm [2] xOp [1]:
match a =* b, op \{ display a \} 
test.asm [2] match [0]:
match a =* b, op \{ display a \} 
processed: display h
error: undefined symbol 'h'.

A better example is this.

Code:

macro xOp op {
match a =* b, op \{ display \`a \} 
} 
;in code
xOp 2*1 ;display 2
xOp h*j ;display h

Code:

flat assembler  version 1.73.31  (16384 kilobytes memory)
2h
1 passes, 0 bytes.

I suspect you are outputting the character 0x02, which is a non-printing character so you don't see it.

See the "blank" line in the output above, there is a character 0x02 hidden there.

And how get Option from match?
I mean symbol * or + or / or -
Using for each symbol separate match?

helped me, chinese karate master Chu Smile

Code:

macro xchu op,do,op1 {
      ueqqu equ 0
      match &a=op &b , op1 \{
            movaps xmm0,dqword [a]
            do xmm0,dqword [b]
            display 'adr;'
            ueqqu equ 1
            \}
      match a=op b , op1 \{
           ; display \`a
           ; display \`b
            if ueqqu = 0
            display 'xmm;'
            do xmm\#\a,xmm\#\b
            end if            \}
}
macro xmOp4 op1 {       
      xchu *,mulps,op1
      xchu /,divps,op1
      xchu +,addps,op1
      xchu -,subps,op1  
      }
;in code 
align 16
p1 dd 1.0,2.0,3.0,4.0
p2 dd 10.0,20.0,30.0,40.0

        xmOp4 &p2-&p1
        xmOp4 0*2
        xmOp4 &p2*&p1
        xmOp4 &p2/&p1
