I would like something like expseg, but how would I
control the curvature of the exponential envelope?
For example, how could I specify a curve like this

                |

And somewhere in between these two curves is a straight line.
Any ideas??

perhaps you could try GEN08 (cubic splines) tho the gradient at both ends
is always zero and you can get some malicious wiggles; the little program
Spliner (Mac only? available at Bath ftp i think) will help with those
