Other Tips I would appreciate...in MPLAB: A confirmation (WITH A "CANCEL" COMMAND) window when leaving MPLAB.. I use WIN95 (sic!) and too often I mis-click the cross (shut-off the program) instead of the "minimize window" box near it (why they are SO CLOSE #%$£ !!!?).. At that point MPLAB will only give me the option to save the Project ( and to lose the register values, the Async Stimulus status and so on...) !!!!! While there is the option CANCEL in the Save Configuration Window.. which is less destructive. Other desired features in MPLAB-SIM : An UNDO function while stepping in.. as in TDebug.. A "Save - registers status" and "Resume old Register values" which could be used together to save a lot of time ( when a point in the program is reached once, whe can resume from there even two days after.. whithout restarting simulation, applying the right stimuli at the pins in the right moments, etc. Any comment? ======================== Bruno Rodeghiero mailto:brurodeg@tin.it Bassano del Grappa (VI) ========================
