First of all, "1_buf" is not a valid variable name in C. Variables
must start with a letter or an underscore; numbers are allowed, but not
at the beginning.
Second, in the above code, you'd want to pass "a" (append) to fopen,
not "wb" (binary write), or it will overwrite whatever used to be in
the file before.
And finally, Blaize had the right idea. Just reuse the code for the
idea/bug/typo commands in do_gen_write (act.other.c) by adding another
SCMD. No need to reinvent the wheel. :)
