RE: HP49-50G VERSION 12.hp SIMPLEX Max Min Pivot Algorithm, multiple/unbounded solutions
Version 12

- In some very special cases, the program could be sometimes "stuck" at the end and chose the wrong row, returning then the second solution — but possibly an unfeasible one.
A special "artificial" test was duly included in subprogram CHECK. 2SOL to fix up that issue.
- The NOTE Var was changed : explanations now only regarding the "pivoting" (outside the program) & no more explanations relative to roundings.
- Lines of explanations in —>PIVOT¦&COL.ROW subprogram suppressed for speed purpose.
