If it is just for mapping the 6 or 7 German Umlaut characters, then
you might give the Posix Shell's "tr" (translate) Utility chance...

 Shell/iX> tr "abc" "ABC" < infile > outfile

The above example replaces all "a" by "A", "b" by "B" anc "c" by "C"
when reading the infile and writing the result to outfile. The two
character list parameters also accept "escaped syntax" like \033 for
octal 33 (i.e. Esc).

As TR.HPBIN.SYS it should also be usable directly from the MPE CI.
