If you are talking about local variables:
Code: struc SS { .val1 rd 4 .val2 dd ? } proc PP, arg1, arg1, arg3 ; declare local variables here with "." in the begining: .local1 SS .local2 dd ? enter mov eax,[.local1.val1+4*2] sub eax, [.local1.val2] add eax, [.local2] return |

No, I want to deliver structure in procedure as argument and then to get acces to any element.
Code: proc PP, arg1 enter mov eax,[arg1.val1] return How can i tell to compiler that the arg1 is structure? _________________ English isn't my native, so sorry for any mistakes I can make... |

proc MyProc1
.rect RECT
enter
.....
lea eax, [.rect]
stdcall MyProc2, eax
....
return
; returns: ecx - width, edx - height of rectangle.
proc MyProc2, ptrRect
enter
mov eax, [ptrRect]
mov ecx, [eax+RECT.right]
mov edx, [eax+RECT.bottom]
sub ecx, [eax+RECT.left]
sub edx, [eax+RECT.top]
return
Help this will help Regards |

Pushing whole structure on stack isn't good programing style, but if you want that modified macro I think should do this (I don't know is this works
 ):
Code: macro proc_ext name,[arg, type] ; define procedure { common name: virtual at ebp+8 if ~ arg eq forward arg type common end if ..ret = $ - (ebp+8) end virtual local ..dynamic_data,..dynamic_size dynamic_data equ ..dynamic_data dynamic_size equ ..dynamic_size virtual at ebp - dynamic_size dynamic_data: } struc some_str { .val1 rd 4 .val2 dd ? } proc_ext PP, var, some_str enter mov eax, [var.val1+4*2] return But how to push structure on stack you have to think. |
