My favorite error message of all time was `unintelligent control
statment was output with diagnostic.' That was on the batch job
control on an CDC 18/20 ITOS system.  It was years later that I
realized that my program had stopped without reading the last record
in the sysin and a data card was the next thing read by the batch
system.  I had put two sentinel numbers as input instead of one.  It
just couldn't figure out what to do with 99999 as a job control card.

The message should have been, `Hey stupid!  What's 99999 supposed to
mean?'
