Ken,
In your example: A0 is an ARRAY variable,
A1 is another (independent) ARRAY variable and so
on. So you have N array variables with different
names.
A[i] is not the same as Ai.
A[i] is i-th element of A array variable.
Ai is the (array) variable that has the name of
Ai
On the other hand you can no create variable names dynamically
like A+i = ..something
You could simplify the code by declaring a
function:
<FONT face="Courier New" color=#000000
size=2>
function
mycolor( array, shift )
<FONT face="Courier New"
size=2>{
array = Ref(
array, shift );
<FONT face="Courier New"
size=2> color<FONT
face="Courier New" color=#000000 size=2> =<SPAN
lang=en-us> <FONT face="Courier New"
color=#0000ff size=2>IIf<SPAN
lang=en-us>(
array<FONT face="Courier New"
color=#000000 size=2><<SPAN
lang=en-us><FONT face="Courier New" color=#ff00ff
size=2>3<SPAN

lang=en-us><FONT face="Courier New" color=#000000
size=2>
AND<SPAN
lang=en-us><FONT face="Courier New"
color=#000000 size=2><SPAN
lang=en-us> array
<FONT face="Courier New" color=#000000
size=2><<SPAN
lang=en-us><FONT face="Courier New" color=#ff00ff
size=2>5<SPAN
lang=en-us><FONT face="Courier New" color=#000000
size=2>,<SPAN
lang=en-us><FONT face="Courier New" color=#ff0000
size=2>colorYellow<SPAN
lang=en-us><FONT face="Courier New" color=#000000

lang=en-us><FONT face="Courier New" color=#ff0000
size=2>colorGreen<SPAN
lang=en-us><FONT face="Courier New" color=#000000
size=2>);
<FONT face="Courier New"
size=2>
return color;
}
and then just write:
A1 = mycolor( Tot, -1 );
A2 = mycolor( Tot, -2 );
A3 = mycolor( Tot, -3 );
A4 = mycolor( Tot, -4 );
A5 = mycolor( Tot, -5
);
<FONT face="Courier New"
size=2>
You would be able to wrap it up in a loop if you could declare
multi-dimensional arrays but you can't do this right now
(unless you use JScript or VBScript)
Please describe your high-level goal.
Quote from "how to ask questions the smart way":
"If you are trying to find out how to do something,begin by
describing the goal. Only then describe the particular step towards it that you
are blocked on.
Often, people who need technical help have a high-level goal in mind and get
stuck on what they think is one particular path towards the goal. They come for
help with the step, but don't realize that the path is wrong. It can take a lot
of effort to get past this."
