One could also write a single long string, with couples of chars. 
Borrowing from the code above:

    sConvert = "?a0b1c2   d3e4f5g6   h7....."

note the spaces in the middle. A routine then can do:

    pos=instr(sConvert, sInChar)
    return mid(sConvert, pos+1,1)   ' if pos=0, then the first character 
is returned...

This is faster to write... and perhaps easier to read/mantain. Of 
course, it works only for single characters; but variations on this 
theme could let it work for other kind of translations.
