Regina REXX Interpreter Reviews

As a Rexx user since 1985 (mainframe, then OS/2, now Windows and Linux), I so very much appreciate Regina Rexx. I really like how my C/C++ executables become the interpreter with the use of the RexxStart() API. There is no spawning a child process to do the interpretation. The running of a script happens in my process, on my thread. I get a result as if I called a subroutine. And while that script is running, it can call back into functions I wrote in C, also like a subroutine. The result is a truly remarkable combination of compiled and interpreted behaviors. Sure, Python can do this too. But it is a simpler thing in Rexx where every variable, even a numeric variable, is a string. So all marshalling between compiled and interpreted code becomes mere string handling. I love it.

Regina had Rexx language level 5 address ... with ... for years, while ooRexx 4.2.0 users still wait for 5.0.0 (apparently almost ready in early 2020, but There Be Dragons.) Arguably ooRexx should support the Regina address system ... idea in addition to its address cmd ... idea for better portability. Likewise Regina should offer DO ... OVER ... (and LOOP ... while at it) as an option. Both interpreters could allow some well-known alien syntax in their tokenization as "not strictly invalid" + runtime syntax error "can't do that" instead of an abnormal end before starting. I'm just dreaming ;-)

thanks see: VRCalc++ OOSL (Script) on sourceforge

REXX is my favorite scripting language. I am impressed that most everything I could do with REXX on OS/2 is available on Windows 10.

Regina-rexx is great! Thanks.

Quick and easy to use. A must have for any computer

Great Job

I love the way I my first rexx program, written on an IBM mainframe in the late 80's, is still running today in more or less the same form, having travelled via unix, linux and all windows versions since 2000. Regina has been the backbone for all that time :-).

Great Job, I find it useful for automating tasks, (Running B2H) etc)

good job

high yield investment

This language does so many things that are so tedious otherwise. Recommended!
