I remember helping newbie students at USC who were very confused that even though they made the changes "PL/C USES", their program didn't work!

It tried automatically to keep things running after a parsing error by inserting some token - semicolon, parenthesis, whatever seemed best - and continuing to parse, in order to maximize the amount of input that could be parsed before giving up. At least, that's what I took the motivation to be. It rarely succeeded in fixing the actual problem, despite PL/I being plastered with semicolons, but it did tend to ferret out more errors per run. I found the tactic helpful.
