Gary,
I was away from C (Borland, yup!) for over 20 years before I took it back up in the CamBam environment with C#.
Is it like the old stuff? Naw. Can you re-learn and re-apply your old skills? Yep.
OOP is still causing me many "oops". But what's changed since I was doing procedural programming is the wealth of help, advice, and examples available now on the web.
You (I) can muddle through, even if you (I) don't fully understand.
