Re: [Oorexx-devel] USE ARG default values with references.

Just to make sure that no other misunderstanding occurs: the default value in USE ARG has been used/applied by ooRexx only, if an argument value was left out when invoking the routine. In the current implementation of a variable reference argument must be always supplied or otherwise a runtime

Re: [Oorexx-devel] USE ARG default values with references.

No, you are not understanding the question. If you use USE ARG >someVar Then the argument is always required. An error will be raised if one is not provided and the reference is not to a matching type. Right now, if you use ">", the default value expression is not allowed. However, I was thinking

Re: [Oorexx-devel] USE ARG default values with references.

carat has some compatibility problems with other Rexx interpreters that interpreted the carat as a logical not. I'd prefer to stay away from that. In any event, I just committed the changes to use '>' rather than '&'. :-))) Many thanks. Mike -

One other point I should probably make related to this is that the referencing operator (currently spelled "&") ... I trust that spelling is still considered an open issue. :-) I'm warming to using '>' on both sides .. at least it implies some sort of movement/look elsewhere. My secon

[Oorexx-devel] USE ARG default values with references.

I have one additional open issue with my variable references prototype, and that's whether to support a default value or not on USE ARG if aliasing is requested. Right now I don't support it at all. There is a case for supporting a default value that would be assigned to the aliased variable if i

[Oorexx-devel] Use case: calling into Rexx while the Rexx interpreter shuts down (crashes Rexx)

There is one use-case for which I am not able to find a work-around: * Rexx loads BSF4ooRexx and interfaces with Java. * For Java event handlers ooRexx objects are passed to Java, such that Java calls back to Rexx (Rexx messages will be sent to the Rexx object, whenever a Java method gets

Re: [Oorexx-devel] use arg with defaults question

The default expression is what's known as a "constant expression". The expression must be either a single string or constant symbol (e.g., a number), or an expression contained in parentheses. This is a construct used in other places (for example, the forward and raise instructions). This is an e

I see that the following code generates an error: ::method someMethod use strict arg num = 32, otherNum = -1 ... Incorrect expression detected at "-" It is easy enough to fix, otherNum = (-1) I was just surprised. Intuitively, it seems it should work without the parens. Is this intentiona
