When dealing with large numbers of subscripts, such as you might encounter in manufacturing or detailed project models, it is convenient to not have to write out all Subscript Element values. To facilitate this you can specify numeric ranges, as in:
lot : (LOT1-LOT3),LOT12,(LOT14-LOT16) ~~|
which is will be expanded to the equivalent:
lot : LOT1,LOT2,LOT3,LOT12,LOT14,LOT15,LOT16 ~~|
You must enclose ranges in parentheses. Everything preceding the numbers must match, and the numbers must increase. Vensim does not allow purely numeric subscripts (i.e., 1,2,3… ).
