There are two compiler options in the IBM Compiler - SLINE and NOSLINE - use of NOSLINE will prevent the sourcelines from being included in the load module.

I have a lot of experience with the Rexx compiler. I can affirm 100% of what @Mark, @Lionel and @Peter write. Your Rexx code will almost certainly run faster, but not an order of magnitude faster. If you are computing prime numbers in Rexx it will probably be a lot faster; if you are reading a big sequential file then probably not much faster. Yes, your original source code is embedded in the load module, so the compiler is zero help if your goal is to "hide" your proprietary logic. It is not in the neatest format, but any 8th grade computer student could readily extract it in readable form. It has to be there -- there is no getting around it -- because of the execution model and to support things like SOURCELINE. Be aware, and this is an important point: the distribution and licensing model is different from any other language: - If I write, compile and bind a COBOL program, then it will either run or not run on any given system. Nowadays every system has LE, so basically it will run on any system, with no licensing charges or considerations for the customer or user. - OTOH if I write, compile and bind a Rexx program, then how it runs on a given target system varies: - If the target system provides the Rexx compiler library then the program will run at full compiled speed. This library is a priced option. - If the target system provides the Rexx "alternate library" then the program will run at standard Rexx interpreted speed. The customer has to install this library, but it is "free." IBM even permits you to provide it to your customers yourself. - If neither of the above then the program will fail.
