The StackFrame class gives access to execution information about an executing Rexx activity. Instances of the StackFrame class can be obtained via the .CONTEXT environment symbol or from a condition object created for a trapped condition. A StackFrame instance represents an instance of an execution unit on the current activity's call stack. It provides information on code location, arguments, etc. that are useful for debugging and problem determination. StackFrame instances cannot be directly created by the user.
