DECM
Computes a sum with the routine specified by
label. Initially, X contains the loop control num-
ber in the format cccccc.fffii and the
sum is set to 0. Each run through the routine
specified computes a summand. At its end, this
summand is added to said sum; the operation
then decrements ccccccc by ii and runs
said routine again if then ccccccc  fff ,
else returns the resulting sum in X.
