hi
i am not sure if i understand you or not , but i think you want to get
the product of a term with subscripts i and b, such that i is not
equal to b.
if this is your problem , you can write the code as follows:
prod((I,b) (ord (i) ne ord(b)), your term(I,b)) If you want to run it such that I is less than b, it will become: prod((I,b) (ord (i) lt ord(b)), your term(I,b))

i hope it is usefull for you
best regards
