- GCOBOL improves MOVE routines and fixes negative zero handling
- tldr

This commit significantly improves GCOBOL’s MOVE routines, specifically addressing the implementation of MOVE COMP-3 to NumericDisplay. It also corrects long-standing errors where truncated moves to numeric-display and packed-decimal formats could create an erroneous “negative zero” value. The fixes involve new routines like clear_negative_zero and expanded test coverage to ensure correct behavior and data integrity.
