Writing null into file

[Przemys³aw Elias]

Hi,

Is it possible to put a ASCII 0 character, which is NULL.
I'm trying to use it in a testbench with a write(line,
character'val(0)); function from std.textio library, but it simply
doesn't work this way.
Any ideas?

Maybe

constant newline_c : string := (1 => NUL);

constant newline_c : string := (1 => NUL);

If that works, you might want to change the name to null_c

You're confused, ASCII 0 character is exactly that, the ASCII
character '0'...which is a byte that has the decimal value of 48, hex
value of 0x30.

character'val(0)); function from std.textio library, but it simply

Whether writing the ASCII character '0' or the NUL character, works
for me using std.textio functions.
