I loved it too. I moved to "C" because of one missing function in Pascal (and as I would say now - it's runtime library) - "movefile" - e.g. moving file from one directory to another.

Also someone was spreading rumours that all games were written in C/C++ so we had to move to it :)

When I learned assembly, and got my Ralph Brown's interrupt list (best thing ever back in the days) I went back to Pascal and made little assembly function for "movefile".

I remmember friend of mine, who just moved to "C" put all his code in the .h file - and it was compiling all the time. Back then having .TPU file and not having to write additional header file was very advanced compared to C/C++ - and the compilation times were much faster.
