 # BASE36 - Add 1 to an Alpha-Numeric String in RPGLE
 
-This is a service program that adds 1 to an alpha-numeric string. The string can be any (sensible) length but is currently set at a arbitrary max of 50 characters.
+This is a service program that adds 1 to an alpha-numeric string. The string can be any (sensible) length but is currently set at an arbitrary max of 50 characters.
 
-The code was originally developed to help out when a numeric key (kept in a character field) was about to hit the maximum, and the company did not want to re-structure their database. I had developed a solution back in RPG III days so converting it to RPGIV was a trivial task.

Instead, they want to use A-Z in the number, so that incrementing 899999 would give 9AAAAA.

 Another potential use might be incrementing a unique alpha numeric part number.

 It is currently set to use a BASE36 character set (A-Z and 0-9) and the raw EBCDIC code sorting sequence, where numbers are higher than characters. Changing either the character set of the sorting sequence simply requires changing two constants.
 
-I've been experimenting with **free** [Visual Studio Code](https://code.visualstudio.com/) and the [Code for IBM i](https://halcyon-tech.github.io/code-for-ibmi/#/) extension to VS Code, so using that I tidied up the code, made it into a service program, made it more flexible and wrote some testing code. Lots of fun and a good learning experience using the new, totally free, D-specs...
