While successful as a notation for mathematical algorithms, it lacked important data types, such as pointers or characters. In the late sixties, several proposals for an evolutionary hospitls img friendly hospitals usmle Ti-83 guidebook
were developed. The most successful one was Pascal, defined in 1970 by Prof. Pascal received a big boost when ETH released a Pascal compiler that produced a simple intermediate code for a virtual machine (P-code), instead of true native code for a particular machine. This img friendly hospitals usmle porting Pascal to other processor architectures considerably, because hoepitals a new P-code interpreter needed be written for this purpose, not a whole new compiler. One of these projects had been undertaken at the University of California, San Diego. This gave Pascal a second important boost.
