EXTERNALS z/OS TSO/E REXX Reference SA32-0972-00 |
|
(Non-SAA Function) EXTERNALS is a non-SAA built-in
function provided only by TSO/E and VM.
>>-EXTERNALS()------------------------------------------------->< always returns a 0. For example:
The EXTERNALS function returns the number of elements in the terminal input buffer (system external event queue). In TSO/E, there is no equivalent buffer. Therefore, in the TSO/E implementation of REXX, the EXTERNALS function always returns a 0. |
