I have some code i found to get the windows version, i am trying to make it 'lower level' so that i can learn masm32/asm better. here is what i have so far -
Any ideas what i am doing wrong?
print macro lpszText:VARARG

.data
txt DB lpszText,13,10,0
.code
invoke StdOut, ADDR txt

Here is a striped down code which should work:
There were just to many errors and stuff that didn't made sense in the code you have provided. So I guess it'll be pointless to explain each fault. However if you have a specific question regarding something, don't hesitate to ask. We will be happy to help.
