What is Structured Programming?
The today usual “structured” programming (only one instruction per program line as well as “opening” and “closing” instructions as IF/ENDIF, REPEAT/UNTIL, FOR/NEXT etc.) was introduced by Professor Wirth under PASCAL and perfected by Frank Ostrowski in its legendary GFA-BASIC as a BASIC variant on the ATARI ST. Today this form of the program structure is considered as international obligatory standard.
