<br>
You got that message because that is exactly what you have done. Global
variables can only be defined in one place in the whole project. Everywhere
else you must use the 'extern' keyword.<br>
<br>
John<br>
<br>
<br>
P.S. Last week Richard said he was going away for a "couple of
years". I hope he only meant a "couple of <b><span style='font-weight:
bold'>weeks</span></b>", but he has been very quiet.<br>

<p class=MsoNormal><font size=2 face="Times New Roman"><span lang=SV
style='font-size:10.0pt'>I got this error:<br>
<br>
!E filename.o(294): multiple define: ‘myVar<br>
<br>
I did have some problems with multiple defined variables because of a bad
#define in a header. But it was not with this variable so I just didn’t
understand a thing until I found out that I had assigned a value to this global
variable and also by mistake assigned it in the place there it was defined as
extern. Like this:<br>
<br>
In main file:<br>
static unsigned char myVar=0;<br>
<br>
In other files:<br>
unsigned char myCar=0;<br>
<br>
Richard: Is it possible that this could result in some other error message than
“multiple define”? Something like “multiple assigning of
predefined value…”<br>
