when and how is bcc called?

When you hit "Build & Run", does the IDE just run bcc with the argument of the path to the file being built? Such as: "bcc ~/BlitzMax/test.bmx". Is this how it is called?

the IDE calls bmk, bmk in turn calls the various compilers for each of the source types.

hmm... would it be possible to add to bmk so that it calls a certain compiler for a certain type of file?

only with source.

Or you could write your own bmk, rename the current one, use your one to call whatever you want then call bmk for the rest.
