Any free mobile IDEs that run on a Blackberry?

I was just wondering if there were any IDEs that I can run on my blackberry. My old Palm had on board C and a BASIC interpreter. On board C used the Palm's builtin text editor but the BASIC interpreter had its own simple editor built in.

Anything like this for Blackberry or j2me in general?

From stackoverflow

• As far as I know, there are no Basic or C interpreters or IDEs that run specifically on the BlackBerry, but there is an open source J2ME basic dialect called CellularBasic which is meant to be coded with/executed on the device itself. It targets J2ME, so it may run on the BlackBerry: http://cellbasic.sourceforge.net/

• I'm working on a Hecl port for BlackBerry, but it's not quite there yet. If you're curious, join the Google Group, where I post updates about the state of things.
