I'm using VBA (Visual Basic 6.3) in Excel 2002.

Can I use VBA to write a program that is made up from a series of
subroutines, or the VBA equivalent? I remember using CALL in FORTRAN years
ago, but what is the corresponding VBA syntax?

Also, can VBA produce simple graphics (this could be a little difficult to
explain). For example as an output from a VBA program a simple diagram is
produced, such as lines, 2-D planes and cylinders. I'm not sure if VBA has
any graphics abilities.

Thanks.
