I created an alphanumeric SAC file with the SAC software (v.101.4)
(using the commands FUNCGEN and WRITE ALPHA) and was wondering about the
first string header line (fields KSTNM & KEVNM, 8+16 chars) which seems
to be one character longer (25) than stated by the manual, see attached
screenshot "sac_alpha.png".

I then manually filled this line with a test value of
"012345670123456789ABCDEFG" and read it in with the SAC software again.
It states the KEVNM header as "012345679ABCDEFG", see attached
screenshot "sac_alpha_line23.png".
From reading the manual I rather expected it to be "0123456789ABCDEF"

It seems the software works with a space of 1 character in the mid of KEVNM.
Is this behavior intended? If so, I think this should be pointed out
more clearly in the online manual.
