Do you need the max length allowed for the dictionary variable or the length in digits of the number of the current value?

Not sure what you mean.. Lets say if you have an entry of 333, you want to return the length as 3, and if you have 23456, you want to return the length as 5. Is that what you need a function for?

If you don't have a value set, you can use the maxvalue function, which will return the highest value supported by the field. This should get you the
length:
length(maketext("%d",maxvalue(ITEM_NAME)));

That function doesn't exist in CSPro 6.3. In CSPro 7.0, which is now in beta, you can write:
keylist(DICT_NAME);
That will return the number of cases.
