Filetab
Filetab is a computer
programming language which is based on
decision tables and features a fixed logic that is useful for processing an input file and producing a report with control breaks. Though it was originally designed for producing reports, the language can do much more than that. By being based on decision tables, both source and object program can be succinct. Often decision tables can be transferred straight from the specification to the program with little modification.
However, it can be easy to fall into producing
write-only code in this language.
Filetab has a long history, originally being designed for use with 80 column
punched cards. It is descended from the DETAB programming language of the 1960s. Originally, Filetab was used on
ICL operating systems, such as George 3 and
VME, but Filetab is now available for
linux.
