As people said before, Pascal is an old and dying language.
It's not about what non-coders tell, more important is what developers think about that language.
C++/Java (and other new languages) are clearly much more secure than Pascal.
Exactly the opposite. It is a bit harder to code in pascal, but overall code is more stable. Typing in Pascal is a lot more strict allowing the programmer to make much less errors. For example in C it is easy to write beyond the length of the string, which results in buffer overflows, and thousands of exploits targeting that.
Anyway, great programs are results of coding skills and not the choice of a language. Have a look at the size of the binary of Pascal Coin - less then 2Mb (and it has an integrated chain explorer)! Now have a look at the size of any other wallets (like Mist for ETH) - you still think that new languages guarantee much more secure and stable products?
