I wander how could I use
integer (or other numeric params) with irp.
I usualy used string and had no problems,
lately I tried to write a macro that would
set bits indexes of wich specified in param with VARARG.
I tried this way:

  sbits macro bits:VARARG

  result=0

   irp n,bits

   ind = 1 SHL n

   result = result OR ind

   endm

  exitm %result

  endm

But I got error warning from MASM about integer usage.

I'm pretty sure about the end.
'Cause I wrote lots of macs like this
(set bits in spesified ranged of least and most segnificant
set)

stmb macro msb,lsb

	exitm %(0-(1 SHL lsb)) AND ((1 SHL (msb+1))-1)

endm

So I think I did something wrong in this part

   irp n,bits

   ind = 1 SHL n

   result = result OR ind

   endm

Could you help, please.
I must admit I'm quite a dummy in macro writing :)
