Q1:
What is the different between "sizeof AA" and sizeof (AA)"?
Q2:
What is the different between "LOCAL A,B,C:ps"and
"LOCAL A:ps
LOCAL B:ps
LOCAL C:ps"
Q3:
Why "A FLOAT -1.0f" is Wrong while "A REAL4 -1.0f" is RIGHT?(in .data)
Q4:
Can I write code like follow:
".data
some data define
.code
some exec code
.data
some data define more
.code
some other code........"
If I can ,than how ml.exe orgnise my .data and .code section?
Thanks for your reply!

Q1: I don't think there's any difference between "sizeof xyz" and "sizeof (xyz)"
Q2: I'm not sure...assuming masm doesn't default to e.g. DWORD for a local variable without a "qualifiedtype" then the way you've written it should produce three variables of type "ps"
the same thing could be achieved with "local A[3]:ps"
Q3: MASM does not have a FLOAT directive. It does have REAL4,REAL8,REAL10 and a few others
Q4:Yes masm will group all .data sections in your source code to a common data section in the executable...likewise for the .code sections

This is the syntax for LOCAL directly from the old MASM help file,
LOCAL name [][:qualifiedtype] [, name [] [:qualifiedtype]]...
In most instances is clearer to write single lines with LOCAL in a procedure.
Unless Ps is an abbreviation for a LOCAL which is a PAINTSTRUCT, its not a MASM data type and will generate an error.

For Q1:
I've received a error message for use sizeof (AA),but when I changed it into sizeof AA,Then ml works well
For Q3:
I've defined
It woks well,but when I use
Then It makes a error

For Q3:
I've defined
A Float 1.0f

A Float -1.0f
Then It makes a error
Question 1:
Post your two source lines with and without the ()'s. I've seen both compile, so it must be in how your implementing it. However, i personally always leave out the brackets...
Question 3:
A dq 1.0
B dq -1.0
Now wasnt that easier ;) . DQ -> Define QuadWord, or 8 byte (64bit) double precision float (a.k.a. Real8). This is not a C++ compiler, so dont try and make it such...
:alright:
NaN
