- This is probably an easy question, but I didn't find it in either of my
- FORTRAN 77 texts. I have a program which has a section labelled BLOCK DATA
- where it defines a bunch of variables as common and fills them with data.
- My question is when is this done, before execution? Is there any official
- description of this? Also this program contains a bunch of subroutines
- that I'd like to place into separate files and link their object files at
- compilation, and I was wondering how to handle common blocks and this
- block data section.

- Thanks.

- P.S. I don't see how multiplying an inverse matrix by a column vector is
- faster than back substitution. (Previous Thread). You don't gain the
- advantage of solving 1 at a time as with back substitution.
