50g

Thanks.  I'll try it.  I was becoming resigned to writing an ASCII text file with most of the major gist of the program to the SD card for copying to a directory on the HP 50g, where I would then edit the file adding the proper symbols.

That's why I suggested you may get by using a plain text editor (like Notepad in Windows) on a file with digraphs. Then you only need Conn4x to transfer it to your 50g.
