Thanks, I applied this with modifications:
  1. No, $(( $i + 1 )) is not portable shell syntax. The portable shell
     syntax is `expr $i + 1`.
     For portable shell syntax, always reference the chapter
     "Portable Shell Programming" [1].
  2. Here too, I like a more descriptive name: 'gen-foo.c', not 'txt4.c'.
     (The original code did not do this, because it was bound to Windows 8+3
     file name limitations, and 'gen-README.de.c' was an invalid file name
     in that environment.)
