They DO have their place, as data structures or to hold information that is infrequently accessed or is inconvenient to manage on the stack. The thing (...)

I hate to admit it, but the version of Turbo C++ I just pulled out is 1.00. I departed from the Borland compiler shortly after acquiring this version and did not keep up with advances. Would I gain any advantages by finding a later version, or (...) (25 years ago, 31-Oct-99, to lugnet.robotics.rcx.legos, lugnet.robotics.rcx, lugnet.robotics.rcx.pbforth)

(...) I'll start by pulling the 4x code into the NQC source base.
