format works on numbers, you need to use scan first to go from
char to ascii code...

I think you have to go by way of the decimal representation:

% info tclversion
7.3
% scan a %c code ; format %x $code
61

Hello,

I tried (invain) to "convert" a character to a hexadecimal representation.
What I want is a way to create e.g. the string 61 (hex. value) from e.g. the character a.

How is this done? I have tried format but %x doesn't seem to do that.

Thanks in advance,
Eddi
