Pancode and boxcharts: structured programming revisited
Dan Jönsson · ACM SIGPLAN Notices · 1987
Some new ideas regarding control structures, program charts, and the relationship between the two are presented. It is claimed that the 'pancode' primitives do, if, repeat, else, also, {, and } suffice to build control structures which are more powerful and more readable than those currently used. It is also demonstrated that an equivalent graphical representation of program structure can be obtained by means of 'boxcharts'.
