Re: Base 31 Conversion

It's to make a double secret number (character string) for a vendor. They're
doing a survey, and they want to have this number for identification. I've
got some VB code, but I'm not sure how to convert it to RPG. Here's the VB
code:

' convert a number to any base
' BASE can be in the range 2-31
' NOTE: we have removed the following characters: 0,1,I,L,O
Public Function NumericToCode(ByVal number)
Dim Index
Dim digits
Dim digitValue
Dim base

base = 31

' check base
If base < 2 Or base > 31 Then Err.Raise 5
' get the list of valid digits
digits = Left("23456789ABCDEFGHJKMNPQRSTUVWXYZ", base)
' convert to the other base
Do While number
digitValue = number Mod base
number = number \ base
NumericToCode = Mid(digits, digitValue + 1, 1) & NumericToCode
Loop

End Function

And I think the RPG could be (using the same variables) like this:

DoW Number <> 0;
digitValue = %Rem(number:base);
number = %Int(number / base);
NumericToCode = %BitAnd(%SubStr(digits, digitValue + 1, 1):NumericToCode);
EndDo;

Does this make sense to anyone?

Sorry, no. What do you base 31 for?

Anyone have a Base 31 converter?
