EFL (programming Language)
EFL is a programming language originated by programmer A.D. Hall in the late 1970s and completed by Stuart Feldman. It was intended to improve on Fortran by adding control structures similar to those of C and was implemented as a preprocessor to a Fortran compiler. Its name is an initialism for ''Extended Fortran Language''. It is roughly a superset of Ratfor Ratfor (short for ''Rational Fortran'') is a programming language implemented as a preprocessor for Fortran#FORTRAN 66, Fortran 66. It provides Structured programming, modern control structures, unavailable in Fortran 66, to replace GOTOs and sta ....

Stuart Feldman
Stuart Feldman is an American computer scientist. He is best known as the creator of the computer software program Make. He was also an author of the first Fortran 77 compiler, was part of the original group at Bell Labs that created the Unix operating system, and participated in development of the ALTRAN and EFL programming languages. Feldman is the president of Schmidt Sciences. He was previously Chief Scientist at Schmidt Futures, and was a member of the dean's External Advisory Board at the University of Michigan School of Information. He was previously Vice President, Engineering, East Coast, at Google, and before that Vice President of Computer Science at IBM Research. Feldman has served on the board of the Computing Research Association (CRA) and of the Association to Advance Collegiate Schools of Business (AACSB International). He was chair of ACM SIGPLAN and founding chair of ACM SIGecom. He was elected the President of the ACM in 2006. Feldman is also a member of ...

C (programming Language)
C (''pronounced'' '' – like the letter c'') is a general-purpose programming language. It was created in the 1970s by Dennis Ritchie and remains very widely used and influential. By design, C's features cleanly reflect the capabilities of the targeted Central processing unit, CPUs. It has found lasting use in operating systems code (especially in Kernel (operating system), kernels), device drivers, and protocol stacks, but its use in application software has been decreasing. C is commonly used on computer architectures that range from the largest supercomputers to the smallest microcontrollers and embedded systems. A successor to the programming language B (programming language), B, C was originally developed at Bell Labs by Ritchie between 1972 and 1973 to construct utilities running on Unix. It was applied to re-implementing the kernel of the Unix operating system. During the 1980s, C gradually gained popularity. It has become one of the most widely used programming langu ...

Ratfor
Ratfor (short for ''Rational Fortran'') is a programming language implemented as a preprocessor for Fortran#FORTRAN 66, Fortran 66. It provides Structured programming, modern control structures, unavailable in Fortran 66, to replace GOTOs and statement numbers. Features Ratfor provides the following kinds of flow-control statements, described by Kernighan and Plauger as "shamelessly stolen from the language C (programming language), C, developed for the Unix, UNIX operating system by Dennis Ritchie, D.M. Ritchie" ("Software Tools", p. 318): * statement grouping with braces * if-else, while, for, do, repeat-until, break, next * "free-form" statements, i.e., not constrained by Fortran format rules * , >=, ... in place of .LT., .GT., .GE., ... * include * # comments For example, the following code if (a > b) else might be translated as IF(.NOT.(A.GT.B))GOTO 1 MAX = A GOTO 2 1 CONTINUE MAX = B 2 CONTINUE The version of Ratfor in ''Softwar ...
