Well, our good friends at Yahoo are at it again. Once again they are deferring mail for no apparent reason. Nothing has changed on my system and yet they haven’t accepted a message to deliver to one of their users in 3 days (maybe more). And, of course, there’s no way to actually contact a …

- Command DefaultsThis may seem to be a no-brainer … but it’s very important to NOT change command parameter defaults on commands in the QSYS library. This is especially true if you use 3rd party software that may not expect your commands to have different defaults. Over the past few weeks I’ve been struggling to help a […]David Gibbs
