1. Hex writing
Hello all,
I want to write hex numbers to a file instead of using strings
because I have to write hex numbers like 00h that can't be
represented on a string, or I don't know how.
I use: printf(id,"%s",{#4C,#00,#00,#00})
But that prints only the L character.
Can anybody help in this?

Because printf is trying to print a null terminated string. The
character following #4C "L" is a zero termination amd is understood by
printf to represent the end of a string. If you want to print the
numeric value you would have to use %d ( decimal ) or %x ( hex ).

Forget what I said about null terminated string I am thinking
in wrong langauge.
The #0 are not printable characters, You have to use %x or %d
to print numbers.

#00 is not a SCREEN printable character. However, it prints
just fine to a file.
Example:
integer id
id = open("temp.tmp", "wb")
--printf(id,"%s",{#4C,#00,#00,#00})
printf(id,"%s",{{#4C,#00,#00,#00}})
Yours is commented. Yours will only print the first character.
Mine should print the whole string. Yours only printed the first
character because it assumes that you have a sequence of strings.
