No there is no difference.
Could even be: Code: tst dd 1 dd 1000000 dd 100000 dd 10000 dd 1000 dd 100 dd 10 Last edited by shutdownall on 03 Sep 2014, 21:29; edited 1 time in total |

Ok. But I get different answer in EAX. Is it something about the addressing of proc locals? Code: format pe console include 'win32axp.inc' ;include 'dbg32.inc' call tester invoke system,"pause>null" invoke exit,0 proc tester locals val dd 31h,32h,33h ;displays whatever dd 34h,35h,36h ;val dd 31h,32h,33h,\ ;displays 34h. Correct ; 34h,35h,36h endl mov eax,[val+12] ;prtreg@ eax ret endp data import library msvcrt,'msvcrt.dll' import msvcrt,\ system,'system',exit,'exit',\ putchar,'putchar',getchar,'getchar' end data On the contrary, the first set of "val" works outside locals. |

The locals macro won't initialise the values for unnamed data declarations. Outside of a proc definition the dd functions normally.

Code:
locals
frac db 0 ;marker 1 bytes
both db 0 ;marker 2 bytes
big db 0 ;marker 3 bytes
small db 0 ;marker 4 bytes
large db 0 ;marker <-------------------- orphaned byte
num dd 0 ;integral part
num2 dd 0 ;fraction part
idx dd 0 ;for small
ndx dd 1 ;For big and large
exponent dd 0
mantissa dd 0.0
copy dd 0.0
y dd 10.0 ;divisor/multiplier
tst dd 1,1000000,100000,\ ;<------ here
10000,1000,100,10
endl
You might want to at least WORD align the stack there. |

That's a great tip. Now my proc behaves as expected when I test it into some big test loop. Thanks guru. |
