Built-In Environment Objects

REXX provides some other environment objects all programs can use. To access these built-in objects, you use the special environment symbols whose first character is `.'.

• methods
  The .methods environment symbol identifies a directory of methods that ::METHOD directives in the currently running program define. The directory indexes are the method names. The directory values are the method objects. Only methods that are not preceded by a ::CLASS directive are in the .methods directory. If there are no such methods, the .methods symbol has the default value of `.METHODS'. Here's an example:

  use arg class, methname
  class~define(methname,.methods['a'])
  ::method a
  use arg text
  say text
  

  .rs
  .rs is set to the return status from any executed command (including those submitted with the ADDRESS instruction). The .rs environment symbol has a value of -1 when a command returns a FAILURE condition, a value of 1 when a command returns an ERROR condition, and a value of 0 when a command indicates successful completion. The value of .rs is also available after trapping of the ERROR or FAILURE condition.

  Note: Commands executed manually while tracing interactively do not change the value of .rs. The initial value of .rs is 0.
