From the user standpoint (I'm not a programmer, but I take an interest, and have rooted around a bit in various source codes), these are my observations:
1) When a program written in C crashes, it may do damnear anything on its way out.
When a program written in Pascal/Delphi crashes, it simply closes down and returns you to the OS.
2) I have an ancient (1990) database program I can't live without. When it was retired from the market, its owner kindly shared source with me, which happened to be in Pascal. There's not a single comment in it, but as I know the program so well, I can tell what nearly all its code does.
I can't say that of the other antique program which I still use and know very well (and have perused much of the source), but is written in C.
I doubt it's entirely coincidence, or even relative marketshare, that's given us those marvelous Obfuscated and Underhanded Code contests for C, but no such for Pascal.
