Ciao Mottadelli,

se tu lavori in IBM, credo che ci siamo conosciuti; se non ci siamo
conosciuti, credo che sia il caso che lo facciamo, dato che anch'io ho
lavorato in ST per anni e ho sviluppato un pacchetto gestionale in ST.

Mi puoi spiegare meglio la tua idea per capirne le implicazioni ?

Ciao

Lorenzo
