that's the way gcc's printf does it ... but could someone test on .NET
and tell the list ?..

Would that be much of an issue on formatting ? ... I thought that was
more concerned with parsing the strings into types ...

Btw, I have some happy news as well ... the parrot CVS now has a 
dotgnu.ops file carrying some of the opcodes needed for supporting
sized integers in parrot (Int32,16,8..) ... So we're moving on the 
parrot front now ..(and now we can add new opcodes if needed)...
