Pessima programmazione, ma allora non c’era internet e per dirne una non sapevo compilare i vari bas (oltre a non avere il compilatore, che costava), e non sapevo proprio a chi chiedere.

La schermata iniziale:

ah ah ah! “La duplicazione del programma è vietata”.
MBC stava per Massimiliano Balestrieri Corporation… guardavo troppa tv.

Non so se possa rilasciare del codice basic sotto GPL… sicuramente quella “duplicazione del programma è vietata” appartiene ad un’ altra epoca, ero un bambino!

SORGENTI

Per lanciare il programma cercare su google un qbasic.exe copiare nella directory dei sorgenti e lanciare
da dos.

QBASIC.EXE PITAGOR.BAS

Giusto per questo post ho modificato il css e il js del “delphi recipe”.
Ecco la ricetta per il basic:
