Hi Marc.
Try this one:

y=(1-(1-x)^n)^(1/n)

This will give you:
 y=x when n=1
 and what you want when n=infinite (or almost)

Special thanks to Martin Gardner where thou shall find the answers.

P.S. Just came back from the Musik Messe at Frankfurt. I did not see the
SHARC Csound anywhere. Too many electric guitars though. Maybe next year...
