Yes, Jeffrey, your suspicion was warranted.  The following will cause a
problem:

        doit(5, TRUE);
        .
        .
}

doit(count, flag)
int count;
BOOL flag;
{
...
}

Since BOOL is a short (i.e., 16 bits unless +l is specified under the compiler)
but the constant TRUE or FALSE is long (32 bits), 'flag' will ALWAYS be zero
in doit().  Aztec, arguably should have seen this and made BOOL typedef'ed to
long, but Amiga is partially at fault, because they've been trying to make
SHORT's go away and replace them with WORD to make life easier, and if this
had been done, this problem would not have arisen.  Hope this helps.

Also, I won't be on here for much longer (sniff), because Commodore views
"outsiders" using their vax to post to read news as a security threat!
I guess they don't need help on here either.
