I'm writing a simple program just to get started (se
below).
mat[i][z] = z; this line generate following error:
cannot implicitly convert expression `z` of type `ulong`

Simple as:
```d
mat[i][z] = cast(char) z;
```
Hi thank you for your reply.
But that gives me a blank result (white space). I have to add
'0' to get the 'source' value from the cast.
```d
mat[i][z] = "0123456789"[z];
```
Other than that, your solution is probably the best. Another
thing you can do is instead of casting, use `(z + '0') & 0x7f`.
The above has the benefit that if you exceed the "expected"
limit, you will get an out of bounds error instead of garbage
characters.
