File Type 2Rexx Source File
.REX File Association 2
Source code file written in the Restructured Extended Executor (Rexx) programming language, a scripting and macro language primarily used to generate reports and process data; contains variables, functions, and other statements that tell the program how to function.
If you change the permissions of the REX file to "executable", you will be able to run the file. REX files are placed in the REXX source library in the Workgroup location by default.
NOTE: There are several free Rexx interpreters available, such as Regina, Reginald, and BRexx, that can open the REX fie.
