Hi David,

Looks like your assembler is broken. One option is to not use the
integrated assembler, but instead use the standalone assembler from
the GNU tool chain.

Rather than using .int as in your following message, you might like to
use .2byte or .4byte which are more explicit about their exact meaning.

HTH,


Jeremy
