I use an int array:

    const int[] cfg_Quote_Counts	= [ 2, 8, 6, 4, 0 ];

and would like to use the number of entries, to size another array:

    int[cfg_Quote_Counts.max] cfg_Section_Found;

For some reason, neither .length nor .max will work, even though with enum, .max seems to be something like .length:

    enum Color { red, blue, green };
    int value[Color.max] = [ blue:6, green:2, red:5 ];

This latter example is from the documentation. And ironically does not compile.

Any idea?

In your source declare ...
#    int[] cfg_Section_Found;

At run time use this instead ...

# // Module constructor.
# static this()
# {
#    cfg_Section_Found.length = cfg_Quote_Counts.length;
# }

I ended up doing this in my function:

    int[] cfg_Section_Found;
    cfg_Section_Found.length = cfg_Quote_Counts.length;
    cfg_Section_Found[] = 0;

alas I am still unclear how your above "static this()" is used.

Simply place it somewhere in a module, e.g. outside of a function?

My mistake. I thought that the 'cfg_Section_Found' was declared at the module level and not inside a function. The "static this()" is used to run code before the main() function is called. It is typically used to initialize module level variables. The way you have now done it is fine for variables declared inside a function.

Yes.

Aha... amazing what D will let you do.
