It is the other way around. I want to avoit lists. I would like to read the array elements from a file, and store then directly into the array. This approach would spare me from writing using a possibly expensive heap hungry intermediate structure.

you're asking me ??  I have no idea.  I can't even figure out which package to use.

However if I had to guess, it seems to me that you want to read the data into a list and then find some ST function which can initialize an array using a list (maybe ?)
