Yeah, that's pretty close. Rexx, like Basic, can be considered a
"simple" language. Batch file language is a "real simple" language.

But in some regards Rexx is quite sophisticated. I'm particularly
impressed with Rexx's looping statement -- "DO" -- which is similar to
"FOR" in Basic but can do a lot more. Fortran and PL/I also have "DO"
statements, but PL/I's is more robust. C has a similar statement but
the way you write it is quite different.

If you ever programmed in Basic or Fortran you can quickly learn to
program in Rexx.
