Title: Oxygen Variable Types
Post by: kryton9 on June 25, 2011, 06:31:54 PM

Charles, I prepared a chart for you to fill out when you have some time. I did a few to show how it is setup. I know this will be helpful to understand all of the variable types in Oxygen better.

I started with a chart from a C reference site, but there are many... I have no idea where to place.

List from Oxygen Help of Variables:

Once you placed them below in the chart,
place a + afterwards for each time placed.
I did a few as an example.

any
asciiz
bool
bstr
bstring
bstring2
byte +
char +
cpu
cstring
double +
dword
ext
extended
gstring
float +
fpu
int
integer
long
mmx
quad
qword
short +
single
string
sys
ubyte
uint +
ulong
void
word
wstring
xmm
zstring

Thanks Kent.

I know there are far too many variable types for comfort. I advocate the use of the sys type wherever possible for 64 bit compatibility. And 90% of programming needs can be met with 5 types: sys string zstring single and double.

I'm going to make a quick reference for Oxygen and help to put on my website, so when you have time, if you can fill that info for me it will be helpful!

I updated the file, if you view it, use courier new size 10 and it should line up nicely.

I still haven't been able to assign 18,446,744,073,709,551,615 to a variable yet.

Code: OxygenBasic

1. quad q = 18446744073709551615
2. print str( q )
3.  
4. extended e = 18446744073709551615
5. print str( e )
6.  
7. 'both cases I get: -9.2233720368547758E+18
