compiler warnings should always be taken seriously. The only time you=20
should dismiss them is when you are sure you are doing things correctly=20
(and even then maybe you should think again).

Basically when the compiler issues a warning it is saying "I think this is=
=20
wrong or there might be problem - but you're the boss".

I haven't used MCC18 so I can't tell you what your problem is or how to=20
fix it but possibly a work around might be to use snprintf + fputs. With=20
snprintf you would format the output in a pre-allocated memory buffer=20
(generating a NUL terminated string), then you would output this with=20
fputs.
