CMS EXEC, or EXEC, is an interpreted, command procedure control, computer programming language used by the CMS EXEC Processor supplied with the IBMVirtual Machine/Conversational Monitor System (VM/CMS) operating system. International Business Machines Corporation (known as IBM or Big Blue; NYSE: IBM) is a multinational computer technology corporation headquartered in Armonk, New York, USA. The company is one of the few information technology companies with a continuous history dating back to the 19th century. ... In computer science, a virtual machine is software that creates a virtualized environment between the computer platform and its operating system, so that the end user can operate software on an abstract machine. ... The Conversational Monitor System (CMS) is a relatively simple interactive computing single-user operating system which was for many years IBMs principal time-sharing product. ... VM/CMS (Virtual Machine/Conversational Monitor System, originally called CP/CMS when it first appeared) is a bundled pair of operating systems used on IBM System/360, System/370, System/390, zSeries, and System z9 mainframes (and compatible systems). ...
CMS EXEC has been superseded by EXEC 2 and REXX. All three — CMS EXEC, EXEC 2 and REXX — continue to be supported by the IBM CMS product. REXX (REstructured eXtended eXecutor) is an interpreted programming language which was developed at IBM. It is a structured high-level programming language which was designed to be both easy to learn and easy to read. ...

EXEC -OUT %1 tells ircII to send the output of subprocess 1 to your channel.
The third form is much like the second, except that it sends to the specified nickname or nicknames (the format of the nicknames is the same as for MSG).
EXEC -WINDOW %1 Sends the output of process 1 to the current window.
