something strange appear. Explain me what happens, please.

first code(works normal):

Code:

format PE Console

include 'win32ax.inc'

;macro def_opt456
  ; {
   macro opt6 param
     {
        define hTFs 0
        match =1,param#.proc
        \{ call param
           define hTFs 1 \}
        match =0,hTFs \{ call [param] \}
     }
   ;}

;def_opt456

define EntryPoint.proc 1

.code
EntryPoint:
        int 3
        opt6 EntryPoint

        invoke ExitProcess,0
.end EntryPoint

in the second code, something strange appear.

Code:

format PE Console

include 'win32ax.inc'

macro def_opt456
   {
   macro opt6 param
     \{
        define hTFs 0
        match =1,param#.proc ;<- here. !!!
        \\{ call param
           define hTFs 1 \\}
        match =0,hTFs \\{ call [param] \\}
     \}
   }

def_opt456

define EntryPoint.proc 1

.code
EntryPoint:
        int 3
        opt6 EntryPoint

        invoke ExitProcess,0
.end EntryPoint

the string "match =1,param#.proc" after preprocessing looks like:
match=1,param.proc

but I pass to this macro an argument.
i think must be something like:
match =1,EntryPoint.proc then match =1,1

what am i miss?
