you mean restore the value of ebp? You just push it in the first place then pop it when you are done before returning.

Isn't the "proc" macro dismisses that memory by itself?

Yes i was try do it in this way:

Code:

proc SearchDisk uses ebx esi edi ebp, StartPath, NameSearchFor, win32_find_data, ProcAddress
pushfd
locals
         ...
endl
         ...
popfd
ret
endp

But i steel have strange situation:
This procedure used about 56MB RAM. Now If I call this procedure in my program two times:

Code:

   invoke   SearchDisk, 'c:','*',WFD, ProcAddress
; at now task manager shold show RAM expandable = before call SearchDisk ??? please tell me if i be mistaken in this point.
; It belongs to remember that the SearchDisk it recurrent procedure.
; Anyway so no happend and after next call need RAM grows
   invoke   SearchDisk, 'd:','*',WFD, ProcAddress

I suspect that it will happend because i not relase memory in right way

I think it's the data that is being added to your data variables
