Think about it this way:
There is only one value of zero. Representing it as hex does not change
the value. When the zero is stringified, it is converted to ASCII 30. To get a
specific ASCII character, use chr(). So what you want is the ASCII NUL which is
chr(0).
- Mark.
When I write to a file, most
everything goes in as 30 or greater. For instance, this
code:
binmode OUT_FILE;
syswrite OUT_FILE, 0x0;
Puts a 30 in the DOS debug
screen’s left pane and puts a 0 in the DOS debug’s right screen.
I understand that an ascii zero is
represented by a hex 30, but I expected that outputting a hex value of 0 would
give me a hex value into the file, but instead it gives an ascii 0 value in
the file.
I can put one value of less than
30 in the file. I can put a space in the file which is hex 20 with this
code:
binmode OUT_FILE;
syswrite OUT_FILE, “ “;
since a space is represented by
hex 20. How do I put the other 29 values below 30 into a
file?
Thanks!
