When this happens to me, I make use of one of the quirks of the TECO text
editor on VMS which writes out text files (variable-length, carriage
return carriage
control).

VAX $ directory /full hobbyist*.txt

VAX $ edit/teco hobbyist-use-only-va.txt
*n[End of File]$l512kex$$

[ TECO prompts with an asterisk, the license file has a line with the
text "[End of File]"
at the end - so non-stop search "n" for it - $ is the <ESC> key or
<CTRL-[>, advance
to the next line (lowercase L "l"), then kill any remaining lines and
<NUL> characters
that pad the last block, and exit]
