- explicit type conversion — (programming) (Or "cast" in C and elsewhere). A programming construct (syntax) to specify that an expression's value should be converted to a different type. For example, in C, to convert an integer (usually 32 bits) to a char (usually 8 bits) we might write: int i = 42; char *p = &buf; *p = (char) i; The expression "(char)" (called a "cast") converts i's value to char type. Casts (including this one) are often not strictly necessary, due to automatic coercions performed by the compiler, but can be used to make the conversion obvious and to avoid warning messages.

- glasgow haskell compiler — (language) (GHC) A Haskell 1.2 compiler written in Haskell by the AQUA project at Glasgow University, headed by Simon Peyton Jones <[email protected]> throughout the 1990's [started?]. GHC can generate either C or native code for SPARC, DEC Alpha and other platforms. It can take advantage of features of gcc such as global register variables and has an extensive set of optimisations. GHC features an extensible I/O system based on a "monad", in-line C code, fully fledged unboxed data types, incrementally-updatable arrays, mutable reference types, generational garbage collector, concurrent threads. Time and space profiling is also supported. It requires GNU gcc 2.1+ and Perl. GHC runs on Sun-4, DEC Alpha, Sun-3, NeXT, DECstation, HP-PA and SGI. E-mail: <[email protected]>.
