This is discussed in TSO/E Rexx Reference for your z/OS release. Get the manual and READ it yourself. The is a help forum, not a read the manual for you forum. You have been told this in other threads; obviously you can't be bothered.
We do know what keyboard you're using; we cannot be expected to help you with keyboard issues. Most more or less standard PC type keyboards have a vertical bar on the same key as the \ character. Most more or less standard 3270 emulator programs will send this character to your mainframe as the EBCDIC vertical bar, 0x4F. This is much less confusing than the ¬ character you asked about in another thread.
