I've modified macros from FASM docs to look like:

Code:

macro define_table name,n1,n2 {
 label name
 repeat (n2-n1+1)
  d1 = '0' + (n1+%) shr 4 and $0F
  d2 = '0' + (n1+%) and $0F
  if (d1 > '9')
   d1 = d1 + 'A'-'9'-1
  end if
  if (d2 > '9')
   d2 = d2 + 'A'-'9'-1
  end if
  dd lbl_#d1#d2
 end repeat
}

and wanted to declare jump tables with it using:

Code:

define_table jt_name,0,255

expecting to get table:

Code:

jt_name:
 dd lbl_00
 dd lbl_01
 ...
 dd lbl_FE
 dd lbl_FF

tell me what i've missed 'cause it's not working
or maybe it's not possible to realize such macros?

don't think its possible, i tried something like this already without any luck
you can use 'fix', but then you would to type out 00 to FF manually

label names are resolved at parsing stage, which is before assembly satge (when values of d1 and d2 are calculated). And "#" is handled at preprocessing stage, even before parsing so it really isn't possible.
