Java isn’t free anymore? Last year, Oracle (the owners of Java) announced they were introducing a new chargeable structure to monetize their hugely adopted JAVA programming environment. So, now using Java Software means you may need to pay for a license! However, if you are using IBM software (like RDi) it comes bundled with a …
Mapping Emulator Function Keys with Laptop Touchpads IBM i PF CMD Keys I like big old physical keyboard buttons for my big old physical fingers, and occasional thumb.

Built-In Functions in RPGLE – %EOF & %FOUND %EOF(filename) This built-in function is used to detect end-of file, beginning of file, or subfile full conditions while performing a file operation.

Covid Facemasks have become a new religion The World Health Organization seems to sum this up very nicely. Listen to medical experts recommend who should wear masks and when to wear one: This is common sense, right? Medical Experts recommend something different to what politicians recommend.

Install a font in INTERFORM400 INTERFORM is an IBM-i application that converts regular *SPLF (Spool files aka reports) into different PDF style layouts. It can add change fonts, graphics, logos, add print logic for data selection, and do other prettification of old dry reports without needing any code changes. So, a few days ago I …
So, a chum of mine on social media just posted this link for the first public presentation from his IBM i Startup called iThusiasm. Looks interesting and I’ve signed up. Why not dive right in? Me. Feeling ithusiastic. 😉 What and Who is iThusiasm? iThusiasm is proudly presenting our inaugural meeting for IBM I professionals! …
