There is no doubt about the adavantages of programming macros and basic code
with an interface made in Excel. Advantages such as portability since pretty

sophisticated research (graduate school) the speed for my programs made on
VBA is much slower than other codes (Fortran, C++ and others). Is it possible
to plan a better memory use and compiling options for future versions of
Excel and its VBA programming capabilities?.

Why don't you create DLLs from your Fortran and C++ codes and call them
from Excel?
