You’ll note that the first few bytes of the file in hex are:

73 72 6d 00 2d 73 00

This equates to the ASCII you saw:

srm.-s.

*but* in fact the “.” are actually a place-holder for a non-printable ASCII character (in this case for the hex value 0x00 aka NUL).

It’s standard in C to use a NUL-terminated string so these 0x00 are probably used to indicate the end of the strings.

What this means is it *might* be possible to have additional options if you *insert* characters between the 0x73 value and the 0x00 value.

Or it might not.
