An earlier reply already  mentioned functions using COBOL 85.
If you don't have COBOL (mentioned in an earlier reply), you might be able
to use the "ctranslate" intrinsic.

I don't know if there is currently a built in table for up-shifting and
downshifting.   When I used to work with "classic" HP3000, I wrote my own
tables, except for  ASCII and EBCDIC.

The length of the table supplied to "ctranslate" is normally 256 bytes.
But, if you can guarantee that no byte in the  input string will have a
value exceeding 127, you can get away with supplying a translation table of
128 bytes.
