Just a note for those folks who did not know Bob all that well, Bob was an exceptional assembler language programmer who had been creating basic compilers since the late 1980s where he took Turbo Basic and developed it into PowerBASIC. His compilers were all hand crafted in assembler with the earlier ones being in 16 bit assembler and his more recent 32 bit compilers written in 32 bit assembler.
Having worked in a couple of Bob's beta teams for his later 32 bit compilers you learned very quickly the range of Bob's tech savvy, massive work load capacity and flexibility as a developer yet he also had a good sense of humour, tended to be reasonably patient in the face of silly questions (some of mine included) and was more than willing to defend his work against the occasional idiot that had little grasp of how much he knew.
His product will continue to be developed as he made provision to keep his work and company going yet like many I am sorry to see his passing, it eventually happens to all but it is a great shame to lose someone of this capacity.
