DECM
Computes a product with the routine specified by
label. Initially, X contains the loop control num-
ber in the format cccccc.fffii and the
product is set to 1. Each run through the routine
specified computes a factor. At its end, this fac-
tor is multiplied with said product; the operation
then decrements ccccccc by ii and runs
said routine again if then ccccccc  fff ,
else returns the resulting product in X.
