Vim question

[arnesten]

When I start vim I want it to automatically set the option makeprg to a certain string.
This could be done by just adding "set makeprg=<string>" to ~/.vimrc, but I want the string to be different depending on if it is a C++ file or Java file that I'm opening.

Do we have any hardcore vim users here that could help me with this rather complex problem?

I think what you need to do is to insert a line or two in the .vimrc file using autocmd bla.... Note quite sure about the syntax though.
