Hi there.Does anybody have any comments on the speed of Visual Basic 
version 1.0 or 2.0 ?  Are the programs compiled by Visual Basic much 
slower than the FORTRAN or C programs?

I am trying to write a program using Visual Basic to do some serious 
number crunching,e.g. sigular value decomposition of a large matrix.
The memory problem can be partially solved using the Windows enviroment
but the speed right now is the major concern.

If somebody has some experience with this problem,can you drop me a line?
By the way,can the Dynamic Link Library files created using FORTRAN or
C compilers increase the speed?

Thanks in advance.

Visual Basic is an interpreter, so it is slower than compiler. If you want fast
operation, compiler your C / Fortran language program into DLL and call it from
Visual Basic. It is as fast as C/Fortran.
