A question here: I thought that if storing Rexx objects in a Rexx
collection they are pinned
and do not get garbage collected.
The stack frame object would not be garbage collected, but the stack frame itself and the things
that it referred to would no longer exist or be valid.
Thank you!
A last question in this context: as a StackFrame object allows access to strings and the executable
(a routine or a method) and target (in case of a method) object, would it be safe to just create a
StringTable and copy all accessible values of the StackFrame to the StringTable using the same names
as index?
I.e. the stack frame values for: arguments (an array), executable (a routine or a method), line (a
string), name (a string), target (an object), traceLine (a string), type (a string). The idea being
that the executable and the target object would get pinned by the StringTable (and there would be no
stack frame related context left that could be erroneously referred to later by a Rexx programmer).
