size -- number of points in the table. Must be a power of 2 or power-of-2 plus 1 (see f statement).
start, end -- first and last value to be stored; the GEN draws a curve that goes from start to end: exp(start) .... exp(end). The points stored are uniformly spaced between these to the table size
rescale -- if not zero the table is not rescaled
Examples
Here is a simple example of the GENexp routine. It uses the file genexp.csd.
