[Oorexx-devel] New ooRexx SVN Projects
All - Is there any objection from anyone on creating two projects in the SVN tree to hold the ooRexx and the Build Machine website files? Lately I have been feeling uneasy about those files not being backed up properly as well as making it easier for everyone to edit those files if necessary. Let me know what you think.

No objections from me. I think this would be a very good thing.

David, sounds like a good idea to me too. -- Mark Miesfeld -- Register Now for Creativity and Technology (CaT), June 3rd, NYC.

[Oorexx-devel] Creating method objects from data may raise a syntax exception
When creating a method object with code supplied from a buffer the
following error may appear, if the data contain LF or CRLF:
F:\test\o4rx\tests\setmethod>test.rex
1 *-* ?
7 *-* m=.method~new("aha", code)
Error 13 running aha line 1: Invalid character in program
Error 13.1: Incorrect character in program "?" ('0D'X)
Is this intended? If so, is there a simple utility at the native layer
to convert that (maybe into semi-colons or into a RexxArrayObject)?

Re: [Oorexx-devel] Creating method objects from data may raise a syntax exception
Carriage LF and CRLF sequences are not part of the Rexx syntax
structures, so they are not accepted when you attempt to create
directly from Rexx code. It has always been that way.
The SendMessage() API gives you access to all of the methods of any of
the classes. You are not limited to just what we've decided to
include as convenience methods. I suspect the string makeArray method
will give you exactly what you want.

Re: [Oorexx-devel] 4702 breaks PipeLines application
I tried your suggestion of using the GetAllContextVariables() method. It fails when I try to read the directory from another thread. I used the context method DirectoryAt() to read the directory. In looking at the interpreter code, it appears to me that using any of the context methods from a different thread will fail. James Johnson Rick McGuire wrote: > Sorry, but no.

I wasn't of course suggesting that you make any changes to what we have right now.Just trying to understand things better. So, from a method context or a call context you can get a thread context. Which is the thread the invoked method or call is executing on. >From an interpreter instance you can use AttachThread() to gain a thread context. Now, with that thread context you can use one of the SendMessage() variants to send messages to objects you know about, even if the objects are executing on another interpreter thread. Is that correct? Mostly looking at this from an ooDialog point of view, where I want to send messages from the Windows message loop thread, for a Windows dialog, back to the ooRexx dialog object. The ooRexx dialog is course executing on a different thread than the Windows message loop. As long as I have a good pointer to the ooRexx object, this will work, correct? >>> Yes, because this operation only requires the services provided by a >>> RexxThreadContext object.

Re: [Oorexx-devel] 4702 breaks PipeLines application
You need to use AttachThread() to request a RexxThreadContext object that is valid on the other threads. Then any of the APIs defined on RexxThreadContext will be available to you.

The additional methods provided by a RexxCallContext allow you to "reach back" into the thing that called you and perform operations. For example, SetContextVariable(). This only has meaning when called when you have something preceding you in the call stack. Note that if the main thread retrieves the value of a stem variable (which will be a Stem object), then the other threads can us the RexxThreadContext obtained from an AttachThread() call to set values in the Stem object. This is a well defined usage because once the object reference is obtained, you're no longer dependent upon the calling context.
