From its release on July 27, 1984, until November 1, 1984, MSPCTRAN.BAS had a serious bug that would often prevent it from working at all. The fix was: change line 400 from: 400 if len(x$) < 4 goto 300 to: 400 if len(x$) < 2 goto 300 and insert line 425: 425 if len(x$) < 3 goto 300 [End of MSPCTRAN.BWR]
