0 Send IBM i Email including SQL Table Data automatically

Have you ever wanted to extract some data out of an IBMi/AS400 file using SQL and then email that data to someone as an Excel Spreadsheet? Now you can… all from one IBMi command without having to write any CL code to do it. Projex4i: DSTDTA command now handles SQL STRINGS for selecting data I […]

0 Update an IBM i file with SQL cursor using SQLRPGLE WHERE CURRENT OF

Using SQL in RPGLE programs is easier than you think. Making the move from RPG native file IO to SQL database IO is really quite straightforward.

0 Green Screen to Web Application in 5 minutes (aka how the AS400 got on the World Wide Web with IBM i)

Twenty years ago… I was typing on a dumb terminal, connected to a great big beige computer called IBM AS/400 with a thick grey Twinax cable. Screens were green on black, text only — or sometimes orange on black if you were posh. The internet was this thing we used to send emails (if you knew […]

If you are reading this blog then chances are you are (a) an RPG Programmer and (b) using SEU to edit your code and (c) you are frustrated that SEU wont syntax check new RPG anymore! It’s time to leap into an RPG EDITOR or be pushed… RDi is bloody good but it’s also a very expensive code […]

0 JSON versus JSONP Tutorial – Resurrected

So, I was searching for information on JSON versus JSONP and, more specifically, how to handle JSONP with IBM i Y.A.J.L and I stumbled across this old archived website.
