Passing Information to a Subroutine z/OS TSO/E REXX User's Guide SA32-0982-00 |
|
An internal subroutine can share variables with its caller. Therefore you can use commonly shared variables to pass information between caller and internal subroutine. You can also use arguments to pass information to and from an internal subroutine. External subroutines, however, cannot share the same variables, and information must pass between them through arguments or some other external way, such as the data stack. |
