That file contains (well I'm a little hazy here, the semantics may not be perfect,) the definitions of all the builtin classes and functions. The builtin classes are defined in Rexx in CoreClasses.orx (and a few other files) and that is used in creating rexx.img. The same thing is done for the OleObject class. The class definition is done in a Rexx file and then that is also used as part of rexx.img. The reason you need to rebuild the interpreter is because that rebuilding will recreate rexx.img with your changes included. > Sorry if the answer to this question is known to everyone else and > published on p3 of the reference, it just takes me by surprise and I feel > the need to know. You are starting to enter the realm of 'documented in the code.' There is no page 3 of the reference to cover this. <grin> > 2) Mark said I can use 'Microsoft's free compiler.

I would get The Microsoft Visual C++ 2005 Express Edition if at all possible. It will be easier to help you, I think. Neither Rick nor I have moved up to the 2008 version yet. I'll do a search in a few minutes and then post a link. You should be able to get a working interpreter build without knowing one end of a brace from another. Although, the end of a brace is '}' and not really that hard to discern. > 3) Suppose I do manage to get the compiler running and I build a version of > ooRexx on my machine, can that version of ooRexx live on the same machine > with the Vanilla version that I need for supporting my work - or do I need > to find another machine to do this on? It can easily live on the same machine provided you take a few steps. I have always just built the whole package, and then you can use the regular install / uninstall to switch between versions. I keep several versions installed on my system and just switch back and forth by killing rxapi and renaming directories. It's very simple, although I recall that I had problems describing it to you. <grin> When you get to this point, we can discuss the alternatives in more detail. -- Mark Miesfeld ------------------------------------------------------------------------- Sponsored by: SourceForge.net Community Choice Awards: VOTE NOW!
