Try to stay current on new methods. It can be overwhelming and downright scary at times because of the uncertainty. Because the IT field changes constantly what may be mainstream today is old news tomorrow. Years ago there was not as much change so the programming languages like RPG / COBOL / FORTRAN / BASIC / ASSEMBLER / PASCAL were widely taught. Not so much today for these languages. Today is C+ / C# / JAVA / VB / PHP and a slew of others. The reason is with the newer technology the old coding languages were not well suited to handle the demand and needs. It’s never to late to changes gears either. I made the switch from RPG to VB and the .NET world after 30+ years in RPG. RPG is not dead but there were more opportunities in todays online/mobile world.
