I think every language has some standard libraries that can be used by the programmer. Maybe in pascal you don't have to explicitely declare them, but they are still there.

Agree. What I meant is... with no external unit (explicit unit declarations) involved, we still able to create a program ...

Unfortunatelly, we had several problems in the past relating that: some codes were AC before the upgrade, and CE after it.

Of course, that'd be the consequences. New version is not always fully compatible with the previous one, no matter they try to be backward compatible. And this is not only ...

I found that UVA uses FreePascal (FPC) v.2.0.0 as the pascal compiler. Since now FPC has upgrade to v.2.0.2 which contains tons of bugs fixed, I recommend UVA to upgrade FPC as well.

I also have some suggestions for FPC users here...

1. FPC is very slow on I/O operation. That's why in some cases ...

I've learned many of programming languages, including C/C++, Java, Pascal, Basic, ASM, etc... but then I choose one that I think the best from all the others... that's (object) Pascal ! Using the great open source multiplatform compiler and IDE... FreePascal and Lazarus . No need to learn other ...

I found that ACM uses FreePascal (FPC) v.2.0.0 as the pascal compiler. Since now FPC has upgrade to v.2.0.2 which contains tons of bugs fixed, I recommend ACM to upgrade FPC as well.
