It is posible, although maybe not recomended, since even palms own
example code uses them... I got it working in the mean time, see

You where right indeed, I'm new to palm developping, probebly a typical
beginners mistake...

Indeed it works and the application isn't even that much bigger (28K
in stead of 24K), an alternative is loading the libc.prc, this also
works...
Thanx for your clear response!
