1647	 WATFOR-The University of Waterloo FORTRAN IV Compiler	 WATFOR is an in-core load-and-go compiler which has been implemented within the IBM operating system. FORTRAN IV was selected as the source language in order to achieve maximum language compatibility with other available compiling systems in particular the IBM FORTRAN IV system. The principal advantage of the WATFOR compiler is that it translates FORTRAN IV programs at speeds of up to statements per second. Since the compiler resides core there is virtually no system overhead and hence large batches of student programs may be processed very efficiently. The compiler also provides extensive error diagnostics during both the compilation and the execution phases of a program run. This feature makes the system attractive to both learners and learned users alike.
